History of Friendship Day in US
Considering the valuable role friends play in our life it was deemed to fit to have a day dedicated to friends and friendship. The United States Congress, in 1935, proclaimed first Sunday of August as the National Friendship Day. Since then, celebration of National Friendship Day became an annual event. The noble idea of honoring the beautiful relationship of friendship caught on with the people and soon Friendship Day became a hugely popular festival.
Following the popularity and success of Friendship Day in US, several other countries adopted the tradition of dedicating a day to friends. Today, Friendship Day is enthusiastically celebrated by several countries across the world including India.
In 1997, the United Nations named Winnie - the Pooh as the world's Ambassador of Friendship.
Importance of Friendship in Bible
The Bible, the primary text of the western civilization, reflects upon friendship as the bond that forms the foundation to human faith, trust and companionship. Following verses from the bible aptly portray the importance of friends:
"Ask and it will be given to you; seek and you will find; knock and the door will be opened to you.”
Matthew 7:7
“Greater love hath no man than this that a man lay down his life for his friends.”
John 15:13-15
Besides, there are several tales from the Old Testament and the New Testament about the value of friendship and how true friendship is a treasure to unearth. A noticeable point is that, both the versions make a difference between the two broad meanings of friendship- one is a mere acquaintance, the other is a more affectionate relation.
In the Old Testament, Abraham is called the “friend of God” because of the intimacy of his relations. God speaks to Moses face to face “as a man…unto his friend” (Ex 33:11). The romantic friendship of Ruth and Naomi, the devotion of the subordinate Hushai for David, or the mutual relation between David and Jonathan - the Old Testament is replete with these interesting tales of friends and friendship.
In the New Testament, the relationship between Jesus and his disciples clearly depicts how human friendship can constantly grow. From being teacher and disciple, to lord and servant their relationship finally grew to an unparalleled friendship.
Importance of Friendship in Mahabharata
In the famous Hindu epic ‘Mahabharata’, Lord Krishna demonstrates the many colors of friendship - affection, romance, brotherhood, protection, guidance, intimacy and even teasing. Friendship is all about these and much more.
PHP htmlentities Function
PHP htmlentities Function
Whenever you allow your users to submit text to your website, you need to be careful that you don't leave any security holes open for malicious users to exploit. If you are ever going to allow user submitted text to be visible by the public you should consider using the htmlentities function to prevent them from running html code and scripts that may be harmful to your visitors.
HTML converted into HTML entities.
For example, the string "<script>" would be converted to "<script>".
By converting the < and > into entities, it prevents the browser from using it
as an HTML element and it prevents the code from running if you were to display some user's
input on your website.
This may seem a little complicated, but if you think of the way a browser works, in separate stages,
it becomes a little easier. Let's look at the way the function htmlentities changes the
data at three different levels: in PHP, in raw HTML and in the web browser. The sample
string is a bad script that will redirect visitors to the malicious user's own website.
The HTML output of the above script would be as follows:
If we had not used htmlentities to convert any HTML code into safe entities, this is
what the raw HTML code would be and it would have redirect a visitor to example.com.
Those two HTML code examples are what you would see if you were to view source on the web page.
However, if you were just viewing the output normally in your browser you would
see the following.
consider removing the ability to let them use HTML. Although this will remove a lot of cool things that
your users can do, like making heavily customized content, it will prevent your site from
a lot of common attacks. With some custom coding you can just remove specific tags
from running, but that is beyond the scope of this lesson.
Just remember, that when allowing users to submit content to your site you are also
giving them access to your website. Be sure you take the proper precautions.

string is a bad script that will redirect visitors to the malicious user's own website.
PHP Code:
// An imaginary article submission from a bad user // it will redirect anyone to example.com if the code is run in a browser $userInput = "I am going to hax0r your site, hahaha! <script type='text/javascript'> window.location = 'http://www.example.com/' </script>'"; //Lets make it safer before we use it $userInputEntities = htmlentities($userInput); //Now we can display it echo $userInputEntities;
The HTML output of the above script would be as follows:
Safe Raw HTML Code:
I am going to hax0r your site, hahaha! <script type='text/javascript'> window.location = 'http://www.example.com/' </script>'
If we had not used htmlentities to convert any HTML code into safe entities, this is

Dangerous Raw HTML Code:

</script>'
Dangerous Display:
You'd see whatever spammer site that the malicious user had sent you to. Probably
some herbal supplement site or weight loss pills would be displayed.

When Would You Use htmlentities?
Anytime you allow users to submit content to your website, that other visitors can see, you shouldconsider removing the ability to let them use HTML. Although this will remove a lot of cool things that
your users can do, like making heavily customized content, it will prevent your site from
a lot of common attacks. With some custom coding you can just remove specific tags

PHP - Magic Quotes
PHP - Magic Quotes
Prior to PHP 6 there was a feature called magic quotes that was created to help protect newbie programmers from writing bad form processing code. Magic quotes would automatically escape risky form data that might be used for SQL Injection with a backslash \. The characters escaped by PHP include: quote ', double quote ", backslash \ and NULL characters.
However, this newbie protection proved to cause more problems than it solved and is not
in PHP 6. If your PHP version is any version before 6 then you should use this lesson
to learn more about how magic quotes can affect you.
The get_magic_quotes_gpc function will return a 0 (off) or a 1 (on). These boolean values
will fit nicely into an if statement where 1 is true and 0 is false.
Magic quotes are enabled
If you received the message "Magic quotes are enabled" then you should definitely
continue reading this lesson, if not feel free to learn about it in case you
are developing for servers that might have quotes on or off.
enabled will escape those potentially risky characters. This form submits to itself, so
you only need to make one file, "magic-quotes.php" to test it out.
This simple form will display to you what magic quotes is doing. If you were to
enter and submit the string: Sandy said, "It's a beautiful day outside and I like to use \'s."
You would receive the following output.
Magic quotes did a number on that string, didn't it? Notice that
there is a backslash before all of those risky characters we talked about earlier.
After magic quotes:
Now say that you wanted to remove the escaping that magic quotes puts in, you have two options:
disable magic quotes or strip the backslashes magic quotes adds.
to add some magic quote checking like our "Are They Enabled?" section above. This way
you won't accidentally be removing slashes that are legitimate in the future if
your PHP's magic quotes setting changes in the future.
Our new output for our string containing risky characters would now be:

in PHP 6. If your PHP version is any version before 6 then you should use this lesson
to learn more about how magic quotes can affect you.
Magic Quotes - Are They Enabled?
First things first, you need to check to see if you have magic quotes enabled on you server.The get_magic_quotes_gpc function will return a 0 (off) or a 1 (on). These boolean values
will fit nicely into an if statement where 1 is true and 0 is false.
PHP Code:
if(get_magic_quotes_gpc()) echo "Magic quotes are enabled"; else echo "Magic quotes are disabled";
Display:
Magic quotes are enabled
If you received the message "Magic quotes are enabled" then you should definitely
continue reading this lesson, if not feel free to learn about it in case you
are developing for servers that might have quotes on or off.
Magic Quotes in Action
Now lets make a simple form processor to show how machines with magic quotesenabled will escape those potentially risky characters. This form submits to itself, so
you only need to make one file, "magic-quotes.php" to test it out.
magic-quotes.php Code:
<?php echo "Altered Text: ".$_POST['question']; ?> <form method='post'> Question: <input type='text' name='question'/><br /> <input type='submit'> </form>
This simple form will display to you what magic quotes is doing. If you were to
enter and submit the string: Sandy said, "It's a beautiful day outside and I like to use \'s."
You would receive the following output.
Display:
Altered Text: Sandy said, \"It\'s a beautiful day outside and I like to use \\\'s.\"
Magic quotes did a number on that string, didn't it? Notice that
there is a backslash before all of those risky characters we talked about earlier.
After magic quotes:
- A backslash \ becomes \\
- A quote ' becomes \'
- A double-quote " becomes \"
Now say that you wanted to remove the escaping that magic quotes puts in, you have two options:
disable magic quotes or strip the backslashes magic quotes adds.
Removing Backslashes - stripslashes()
Before you use PHP's backslash removal function stripslashes it's smartto add some magic quote checking like our "Are They Enabled?" section above. This way
you won't accidentally be removing slashes that are legitimate in the future if
your PHP's magic quotes setting changes in the future.
magic-quotes.php Code:
<?php
echo "Removed Slashes: ";
// Remove those slashes
if(get_magic_quotes_gpc())
echo stripslashes($_POST['question']);
else
echo $_POST['question'];
?>
<form method='post'>
Question: <input type='text' name='question'/><br />
<input type='submit'>
</form>
Our new output for our string containing risky characters would now be:
Display:
Removed Slashes: Sandy said, "It's a beautiful day outside and I like to use \'s."
PHP - POST & GET
PHP - POST & GET
Recall from the PHP Forms Lesson where we used an HTML form and sent it to a PHP web page for processing. In that lesson we opted to use the the post method for submitting, but we could have also chosen the get method. This lesson will review both transferring methods.
used the post method. This is what the pertinent line of HTML code looked like:
This HTML code specifies that the form data will be submitted to the "process.php" web
page using the POST method. The way that PHP does this is to store all the "posted"
values into an associative array called "$_POST". Be sure to take notice the names
of the form data names, as they represent the keys in the "$_POST" associative array.
Now that you know about associative arrays,
the PHP code from "process.php" should make a litte more sense.
The form names are used as the keys in the associative array, so be
sure that you never have two input items in your HTML form that have the same name. If you do, then
you might see some problems arise.
we were to change our HTML form to the get method, it would look like this:
The get method is different in that it passes the variables along
to the "process.php" web page by appending them onto the end of the URL. The URL, after clicking submit,
would have this added on to the end of it:
"?item=##&quantity=##"
The question mark "?" tells the browser that the following items are variables. Now that we changed
the method of sending information on "order.html", we must change the "process.php" code
to use the "$_GET" associative array.
After changing the array name the script will function properly. Using
the get method displays the variable information to your visitor, so be sure
you are not sending password information or other sensitive items with the get method.
You would not want your visitors seeing something they are not supposed to!

$quantity = $_POST['quantity']; $item = $_POST['item'];
sure that you never have two input items in your HTML form that have the same name. If you do, then
you might see some problems arise.
PHP - GET
As we mentioned before, the alternative to the post method is get. Ifwe were to change our HTML form to the get method, it would look like this:
HTML Code Excerpt:
<form action="process.php" method="get"> <select name="item"> ... <input name="quantity" type="text" />
The get method is different in that it passes the variables along

the get method displays the variable information to your visitor, so be sure
you are not sending password information or other sensitive items with the get method.
You would not want your visitors seeing something they are not supposed to!
Security Precautions
Whenever you are taking user input and using you need to be sure that the input is safe. If you are going to insert the data into a MySQL database, then you should be sure you have thought about preventing MySQL Injection. If you are going to make a user's input available to the public, then you should think about PHP htmlentities.PHP - Do While Loop
PHP - Do While Loop
A "do while" loop is a slightly modified version of the while loop. If you recal from one of the previous lessons on While Loops the conditional statement is checked comes back true then the code within the while loop is executed. If the conditional statement is false then the code within the loop is not executed.
a conditional statement that is always false. First the while loop:
As you can see, this while loop's conditional statement failed (0 is not greater than 1), which means the code
within the while loop was not executed. Now, can you guess what will happen with
a do-while loop?
The code segment "Mmmm...I love cookies!" was executed even though the conditional
statement was false. This is because a do-while loop first do's and secondly checks the
while condition!
Chances are you will not need to use a do while loop in most of your PHP programming, but it
is good to know it's there!

$cookies = 0; while($cookies > 1){ echo "Mmmmm...I love cookies! *munch munch munch*"; }
Display:
within the while loop was not executed. Now, can you guess what will happen with
a do-while loop?
PHP Code:
$cookies = 0; do { echo "Mmmmm...I love cookies! *munch munch munch*"; } while ($cookies > 1);
Display:
Mmmmm...I love cookies! *munch munch munch*
The code segment "Mmmm...I love cookies!" was executed even though the conditional
statement was false. This is because a do-while loop first do's and secondly checks the
while condition!
Chances are you will not need to use a do while loop in most of your PHP programming, but it
is good to know it's there!
PHP - For Loop
PHP - For Loop
The for loop is simply a while loop with a bit more code added to it. The common tasks that are covered by a for loop are:
Set a counter variable to some initial value.
Check to see if the conditional statement is true.
Execute the code within the loop.
Increment a counter at the end of each iteration through the loop.
The for loop allows you to define these steps in one easy line of code.
It may seem to have a strange form, so pay close attention to the syntax used!
it could be done in a for loop. The basic structure of the for loop is as
follows:
Notice how all the steps of the loop are taken care of in the for loop
statement. Each step is separated by a semicolon: initiliaze counter, conditional statement, and the
counter increment. A semicolon is needed because these are separate expressions. However, notice
that a semicolon is not needed after the "increment counter" expression.
Here is the example of the brush prices done with a for loop .
It is important to note that both the for loop and while loop
implementation of the price chart table are both OK at getting the job done. However,
the for loop is somewhat more compact and would be preferable in this situation. In
later lessons we will see where the while loop should be used instead of the for loop.
PHP For Each Loop
Imagine that you have an associative array that you want to iterate through. PHP provides an easy way to use every element of an array with the Foreach statement.
In plain english this statement will do the following:
While Loop will continue
until some condition fails, the For Each loop will continue until
it has gone through every item in the array.
company as the keys with the values being their age. We want
to know how old everyone is at work so we use a Foreach loop to print
out everyone's name and age.
The syntax of the foreach statement is a little strange, so let's talk about it some.
$employeeAges associative array I want to refer to the key as $key and the value as $value.
The operator "=>" represents the relationship between a key and value. You can imagine that
the key points => to the value. In our example we named the key $key and the value $value.
However, it might be easier to think of it as $name and $age. Below our example does this and notice how the output
is identical because we only changed the variable names that refer to the keys and values.

For Loop Example
Let us take the example from the while loop lesson and see howit could be done in a for loop. The basic structure of the for loop is as
follows:
Pseudo PHP Code:
for ( initialize a counter; conditional statement; increment a counter){ do this code; }
Notice how all the steps of the loop are taken care of in the for loop
statement. Each step is separated by a semicolon: initiliaze counter, conditional statement, and the
counter increment. A semicolon is needed because these are separate expressions. However, notice
that a semicolon is not needed after the "increment counter" expression.
Here is the example of the brush prices done with a for loop .
PHP Code:
$brush_price = 5; echo "<table border=\"1\" align=\"center\">"; echo "<tr><th>Quantity</th>"; echo "<th>Price</th></tr>"; for ( $counter = 10; $counter <= 100; $counter += 10) { echo "<tr><td>"; echo $counter; echo "</td><td>"; echo $brush_price * $counter; echo "</td></tr>"; } echo "</table>";
Display:
Quantity | Price |
---|---|
10 | 50 |
20 | 100 |
30 | 150 |
40 | 200 |
50 | 250 |
60 | 300 |
70 | 350 |
80 | 400 |
90 | 450 |
100 | 500 |
It is important to note that both the for loop and while loop
implementation of the price chart table are both OK at getting the job done. However,
the for loop is somewhat more compact and would be preferable in this situation. In

PHP For Each Loop
Imagine that you have an associative array that you want to iterate through. PHP provides an easy way to use every element of an array with the Foreach statement.
In plain english this statement will do the following:
- For each item in the specified array execute this code.
While Loop will continue
until some condition fails, the For Each loop will continue until
it has gone through every item in the array.
PHP For Each: Example
We have an associative array that stores the names of people in ourcompany as the keys with the values being their age. We want
to know how old everyone is at work so we use a Foreach loop to print
out everyone's name and age.
PHP Code:
$employeeAges; $employeeAges["Lisa"] = "28"; $employeeAges["Jack"] = "16"; $employeeAges["Ryan"] = "35"; $employeeAges["Rachel"] = "46"; $employeeAges["Grace"] = "34"; foreach( $employeeAges as $key => $value){ echo "Name: $key, Age: $value <br />"; }
Display:
Name: Lisa, Age: 28
Name: Jack, Age: 16
Name: Ryan, Age: 35
Name: Rachel, Age: 46
Name: Grace, Age: 34
Name: Jack, Age: 16
Name: Ryan, Age: 35
Name: Rachel, Age: 46
Name: Grace, Age: 34
The syntax of the foreach statement is a little strange, so let's talk about it some.
Foreach Syntax: $something as $key => $value
This crazy statement roughly translates into: For each element of the$employeeAges associative array I want to refer to the key as $key and the value as $value.
The operator "=>" represents the relationship between a key and value. You can imagine that
the key points => to the value. In our example we named the key $key and the value $value.
However, it might be easier to think of it as $name and $age. Below our example does this and notice how the output

Display:
Name: Lisa, Age: 28
Name: Jack, Age: 16
Name: Ryan, Age: 35
Name: Rachel, Age: 46
Name: Grace, Age: 34
Name: Jack, Age: 16

PHP - While Loop
PHP - While Loop
Repetitive tasks are always a burden to us. Deleting spam email, sealing 50 envelopes, and going to work are all examples of tasks that are repeated. The nice thing about programming is that you can avoid such repetitive tasks with a little bit of extra thinking. Most often these repetitive tasks are conquered in the loop.
The idea of a loop is to do something over and over again until the task
has been completed. Before we show a real example of when you might need one,
let's go over the structure of the PHP while loop.
as the specified conditional statement is true. This logical check is the same
as the one that appears in a PHP if statement to determine if it is true or false.
Here is the basic structure of a PHP while loop:
This isn't valid PHP code, but it displays how the while loop is structured.
Here is the break down of how a while loop functions when your script is executing:
like to print out the price chart for number of brushes and total cost.
You sell brushes at a flat rate, but would like to display how much
different quantities would cost. This will save your customers from having to
do the mental math themselves.
You know that a while loop would be perfect for this repetitive and boring task.
Here is how to go about doing it.
Pretty neat, huh? The loop created a new table row and its respective entries
for each quantity, until our counter variable grew past the size of 100. When it
grew past 100 our conditional statement failed and the loop stopped being used. Let's review
what is going on.
You may have noticed that we placed slashes
infront the quotations in the first echo statement. You have to place slashes
before quotations if you do not want the quotation to act as the end of the echo statement.
This is called escaping a character and it is discussed in our PHP Strings lesson.
With proper use of loops you can complete large tasks
with great ease.

let's go over the structure of the PHP while loop.
Simple While Loop Example
The function of the while loop is to do a task over and over as longas the specified conditional statement is true. This logical check is the same
as the one that appears in a PHP if statement to determine if it is true or false.
Here is the basic structure of a PHP while loop:
Pseudo PHP Code:
while ( conditional statement is true){ //do this code; }
Here is the break down of how a while loop functions when your script is executing:
- The conditional statement is checked. If it is true, then (2) occurs. If it is false, then (4) occurs.
- The code within the while loop is executed.
- The process starts again at (1). Effectively "looping" back.
- If the conditional statement is false, then the code within is not executed and there is no more looping. The code following
the while loop is then executed like normal.
A Real While Loop Example
Imagine that you are running an art supply store. You wouldlike to print out the price chart for number of brushes and total cost.
You sell brushes at a flat rate, but would like to display how much
different quantities would cost. This will save your customers from having to
do the mental math themselves.
You know that a while loop would be perfect for this repetitive and boring task.

Pseudo PHP Code:
$brush_price = 5; $counter = 10; echo "<table border=\"1\" align=\"center\">"; echo "<tr><th>Quantity</th>"; echo "<th>Price</th></tr>"; while ( $counter <= 100 ) { echo "<tr><td>"; echo $counter; echo "</td><td>"; echo $brush_price * $counter; echo "</td></tr>"; $counter = $counter + 10; } echo "</table>";
Display:
Quantity | Price |
---|---|
10 | 50 |
20 | 100 |
30 | 150 |
40 | 200 |
50 | 250 |
60 | 300 |
70 | 350 |
80 | 400 |
90 | 450 |
100 | 500 |
Pretty neat, huh? The loop created a new table row and its respective entries
for each quantity, until our counter variable grew past the size of 100. When it
grew past 100 our conditional statement failed and the loop stopped being used. Let's review
what is going on.
- We first made a $brush_price and $counter variable and
set them equal to our desired values. - The table was set up with the beginning table tag and the table headers.
- The while loop conditional statement was checked, and $counter (10) was indeed
smaller or equal to 100. - The code inside the while loop was executed, creating a new table row for the price
of 10 brushes. - We then added 10 to $counter to bring the value to 20.
- The loop started over again at step 3, until $counter grew larger than 100.
- After the loop had completed, we ended the table.
You may have noticed that we placed slashes
infront the quotations in the first echo statement. You have to place slashes
before quotations if you do not want the quotation to act as the end of the echo statement.
This is called escaping a character and it is discussed in our PHP Strings lesson.

PHP Array
PHP Array
An array is a data structure that stores one or more values in a single value. For experienced programmers it is important to note that PHP's arrays are actually maps (each key is mapped to a value).
understand the concept of an array. Imagine that you own a business and
you want to store the names of all your employees in a PHP variable. How
would you go about this?
It wouldn't make much sense to have to store each name
in its own variable. Instead, it would be nice to store all the employee names inside
of a single variable. This can be done, and we show you how below.
In the above example we made use of the key / value structure of an array. The keys
were the numbers we specified in the array and the values were the names of the employees.
Each key of an array represents a value that we can manipulate and reference. The
general form for setting the key of an array equal to a value is:
If we wanted to reference the values that we stored into our array, the following
PHP code would get the job done.
Note: As you may have noticed from the above code example, an array's keys start from 0 and not 1. This is a very common problem for many new programmers who are used to counting from 1 and lead to "off by 1" errors. This is just something that will take experience before you are fully comfortable with it.
PHP arrays are quite useful when used in conjunction with
loops, which we will talk about in a later lesson. Above we showed
an example of an array that made use of integers for the keys (a numerically indexed
array). However, you can also specify a string as the key, which is referred to as an associative array.
to store the salaries of your employees in an array, a numerically indexed array would
not be the best choice. Instead, we could use the employees names as the keys in our
associative array, and the value would be their respective salary.
Once again, the usefulness of arrays will become more apparent
once you have knowledge of for and while loops.
An array is a data structure that stores one or more values in a single value. For experienced programmers it is important to note that PHP's arrays are actually maps (each key is mapped to a value).
PHP - A Numerically Indexed Array
If this is your first time seeing an array, then you may not quiteunderstand the concept of an array. Imagine that you own a business and
you want to store the names of all your employees in a PHP variable. How
would you go about this?
It wouldn't make much sense to have to store each name
in its own variable. Instead, it would be nice to store all the employee names inside
of a single variable. This can be done, and we show you how below.
PHP Code:
$employee_array[0] = "Bob"; $employee_array[1] = "Sally"; $employee_array[2] = "Charlie"; $employee_array[3] = "Clare";
In the above example we made use of the key / value structure of an array. The keys
were the numbers we specified in the array and the values were the names of the employees.
Each key of an array represents a value that we can manipulate and reference. The
general form for setting the key of an array equal to a value is:
- $array[key] = value;

This is just something that will take experience before you are fully comfortable with it.
PHP Code:
echo "Two of my employees are " . $employee_array[0] . " & " . $employee_array[1]; echo "<br />Two more employees of mine are " . $employee_array[2] . " & " . $employee_array[3];
Display:
Two of my employees are Bob & Sally
Two more employees of mine are Charlie & Clare
Two more employees of mine are Charlie & Clare

an example of an array that made use of integers for the keys (a numerically indexed
array). However, you can also specify a string as the key, which is referred to as an associative array.
PHP - Associative Arrays
In an associative array a key is associated with a value. If you wantedto store the salaries of your employees in an array, a numerically indexed array would
not be the best choice. Instead, we could use the employees names as the keys in our
associative array, and the value would be their respective salary.
PHP Code:
$salaries["Bob"] = 2000; $salaries["Sally"] = 4000; $salaries["Charlie"] = 600; $salaries["Clare"] = 0; echo "Bob is being paid - $" . $salaries["Bob"] . "<br />"; echo "Sally is being paid - $" . $salaries["Sally"] . "<br />"; echo "Charlie is being paid - $" . $salaries["Charlie"] . "<br />"; echo "Clare is being paid - $" . $salaries["Clare"];
Display:
Bob is being paid - $2000
Sally is being paid - $4000
Charlie is being paid - $600
Clare is being paid - $0
Sally is being paid - $4000
Charlie is being paid - $600
Clare is being paid - $0
Once again, the usefulness of arrays will become more apparent
once you have knowledge of for and while loops.
PHP - Functions
PHP - Functions
A function is just a name we give to a block of code that can be executed whenever we need it. This might not seem like that big of an idea, but believe me, when you understand and use functions you will be able to save a ton of time and write code that is much more readable!
For example, you might have a company motto that you have to display at least once on every webpage. If you don't, then you get fired! Well, being the savvy PHP programmer you are, you think to yourself, "this sounds like a situation where I might need functions."
Tip: Although functions are often thought of as an advanced topic for beginning programmers to learn, if you take it slow and stick with it, functions can be just minor speedbump in your programming career. So don't give up if you functions confuse you at first!
When you create a function, you first need to give it a name, like myCompanyMotto.
It's with this function name that you will be able to call upon your function, so make it easy to type and understand.
The actual syntax for creating a function is pretty self-explanatory, but you can be the judge of that.
First, you must tell PHP that you want to create a function. You do this by typing the keyword function followed
by your function name and some other stuff (which we'll talk about later).
Here is how you would make a function called myCompanyMotto. Note: We still have
to fill in the code for myCompanyMotto.
Note: Your function name can start with a letter or underscore "_", but not a number!
With a properly formatted function in place, we can now fill in the code that we want our
function to execute. Do you see the curly braces in the above example "{ }"? These braces define
where our function's code goes. The opening curly brace "{" tells php that the function's code is starting and a closing
curly brace "}" tells PHP that our function is done!
We want our function to print out the company motto each time it's called, so that sounds like it's a job for the echo command!
That's it! You have written your first PHP function from scratch! Notice that the code that appears within a function is just the same as any other PHP code.
is a simple PHP script. Let's do two things: add the function code to it and use the function twice.
Although this was a simple example, it's important to understand that there
is a lot going on and there are a lot of areas to make errors. When you are creating a function, follow
these simple guidelines:
the function can then use. Our first function myCompanyMotto isn't all that
useful because all it does, and ever will do, is print out a single, unchanging string.
However, if we were to use parameters, then we would be able to add some extra functionality!
A parameter appears with the parentheses "( )" and looks just like a normal PHP variable.
Let's create a new function that creates a custom greeting based off of a person's name.
Our parameter will be the person's name and our function will concatenate this
name onto a greeting string. Here's what the code would look like.
When we use our myGreeting function we have to send it a string containing someone's name, otherwise
it will break. When you add parameters, you also add more responsibility to you, the programmer!
Let's call our new function a few times with some common first names.
Hello there Jack!
Hello there Ahmed!
Hello there Julie!
Hello there Charles!
It is also possible to have multiple parameters in a function. To separate multiple parameters
PHP uses a comma ",". Let's modify our function to also include last names.
However, a function can only return one thing, although that thing can be any integer, float, array, string, etc. that you choose!
How does it return a value though? Well, when the function is used and finishes executing, it sort of changes from being a function name into being a value. To capture this value you can set a variable equal to the function. Something like:
Let's demonstrate this returning of a value by using a simple function that returns the sum of two integers.
When we first print out the value of $myNumber it is still set to the original value of 0.
However, when we set $myNumber equal to the function mySum, $myNumber
is set equal to mySum's result. In this case, the result was 3 + 4 = 7, which was successfully
stored into $myNumber and displayed in the second echo statement!
are having a hard time understanding lessons, the best piece of advice would be to do your best
the first time, then be sure to come back tomorrow and next week and see if it makes
anymore sense. Chances are, after going through this tutorial more than once, with
breaks in between, this topic will be mastered.

We want our function to print out the company motto each time it's called, so that sounds like it's a job for the echo command!
PHP Code:
<?php
function myCompanyMotto(){
echo "We deliver quantity, not quality!<br />";
}
?>
That's it! You have written your first PHP function from scratch! Notice that the code that appears within a function is just the same as any other PHP code.
Using Your PHP Function
Now that you have completed coding your PHP function, it's time to put it through a test run. Belowis a simple PHP script. Let's do two things: add the function code to it and use the function twice.
PHP Code:
<?php echo "Welcome to Tizag.com <br />"; echo "Well, thanks for stopping by! <br />"; echo "and remember... <br />"; ?>
PHP Code with Function:
<?php function myCompanyMotto(){ echo "We deliver quantity, not quality!<br />"; } echo "Welcome to Tizag.com <br />"; myCompanyMotto(); echo "Well, thanks for stopping by! <br />"; echo "and remember... <br />"; myCompanyMotto(); ?>
Display:
Welcome to Tizag.com
We deliver quantity, not quality!
Well, thanks for stopping by!
and remember...
We deliver quantity, not quality!
We deliver quantity, not quality!
Well, thanks for stopping by!
and remember...
We deliver quantity, not quality!
Although this was a simple example, it's important to understand that there
is a lot going on and there are a lot of areas to make errors. When you are creating a function, follow
these simple guidelines:
- Always start your function with the keyword function
- Remember that your function's code must be between the "{" and the "}"
- When you are using your function, be sure you spell the function name correctly
- Don't give up!
PHP Functions - Parameters
Another useful thing about functions is that you can send them information thatthe function can then use. Our first function myCompanyMotto isn't all that
useful because all it does, and ever will do, is print out a single, unchanging string.
However, if we were to use parameters, then we would be able to add some extra functionality!
A parameter appears with the parentheses "( )" and looks just like a normal PHP variable.
Let's create a new function that creates a custom greeting based off of a person's name.
Our parameter will be the person's name and our function will concatenate this
name onto a greeting string. Here's what the code would look like.
PHP Code with Function:
<?php function myGreeting($firstName){ echo "Hello there ". $firstName . "!<br />"; } ?>
When we use our myGreeting function we have to send it a string containing someone's name, otherwise
it will break. When you add parameters, you also add more responsibility to you, the programmer!
Let's call our new function a few times with some common first names.
PHP Code:
<?php function myGreeting($firstName){ echo "Hello there ". $firstName . "!<br />"; } myGreeting("Jack"); myGreeting("Ahmed"); myGreeting("Julie"); myGreeting("Charles"); ?>
Display:
Hello there Jack!
Hello there Ahmed!
Hello there Julie!
Hello there Charles!
It is also possible to have multiple parameters in a function. To separate multiple parameters
PHP uses a comma ",". Let's modify our function to also include last names.
PHP Code:
<?php function myGreeting($firstName, $lastName){ echo "Hello there ". $firstName ." ". $lastName ."!<br />"; } myGreeting("Jack", "Black"); myGreeting("Ahmed", "Zewail"); myGreeting("Julie", "Roberts"); myGreeting("Charles", "Schwab"); ?>
Display:
Hello there Jack Black!
Hello there Ahmed Zewail!
Hello there Julie Roberts!
Hello there Charles Schwab!
Hello there Ahmed Zewail!
Hello there Julie Roberts!
Hello there Charles Schwab!
PHP Functions - Returning Values
Besides being able to pass functions information, you can also have them return a value.However, a function can only return one thing, although that thing can be any integer, float, array, string, etc. that you choose!
How does it return a value though? Well, when the function is used and finishes executing, it sort of changes from being a function name into being a value. To capture this value you can set a variable equal to the function. Something like:
- $myVar = somefunction();
Let's demonstrate this returning of a value by using a simple function that returns the sum of two integers.
PHP Code:
<?php function mySum($numX, $numY){ $total = $numX + $numY; return $total; } $myNumber = 0; echo "Before the function, myNumber = ". $myNumber ."<br />"; $myNumber = mySum(3, 4); // Store the result of mySum in $myNumber echo "After the function, myNumber = " . $myNumber ."<br />"; ?>
Display:
Before the function, myNumber = 0
After the function, myNumber = 7
After the function, myNumber = 7
When we first print out the value of $myNumber it is still set to the original value of 0.
However, when we set $myNumber equal to the function mySum, $myNumber
is set equal to mySum's result. In this case, the result was 3 + 4 = 7, which was successfully
stored into $myNumber and displayed in the second echo statement!
PHP Functions - Practice Makes Perfect
If you are new to programming, then this lesson might or might not seem like overkill. If youare having a hard time understanding lessons, the best piece of advice would be to do your best
the first time, then be sure to come back tomorrow and next week and see if it makes
anymore sense. Chances are, after going through this tutorial more than once, with

PHP Switch Statement
PHP Switch Statement
In the previous lessons we covered the various elements that make up an If Statement in PHP. However, there are times when an if statement is not the most efficient way to check for certain conditions.
For example we might have a variable that stores travel destinations and you want
to pack according to this destination variable. In this example you might have
20 different locations that you would have to check with a nasty long block
of If/ElseIf/ElseIf/ElseIf/... statements. This doesn't sound like much fun to code,
let's see if we can do something different.
conditions at once, and the great thing is that it is actually more efficient
programming to do this. A true win-win situation!
The way the Switch statement works is it takes a single variable as input
and then checks it against all the different cases you set up for that
switch statement. Instead of having to check that variable one at a time,
as it goes through a bunch of If Statements, the Switch statement only has to check
one time.
In our example the single variable will be $destination
and the cases will be: Las Vegas, Amsterdam, Egypt, Tokyo, and the Caribbean Islands.
operating on $destination in immediately did a search for a case with the
value of "Tokyo". It found it and proceeded to execute the code that existed
within that segment.
You might have noticed how each case contains a break; at the end of its code area. This
break prevents the other cases from being executed. If the above example did not
have any break statements then all the cases that follow Tokyo would have been executed as well.
Use this knowledge to enhance the power of your switch statements!
The form of the switch statement is rather unique, so spend some time reviewing it
before moving on. Note: Beginning programmers should always include the break; to
avoid any unnecessary confusion.
variable doesn't match our condition. The if statement has the else clause and
the switch statement has the default case.
It's usually a good idea to always include the default case in all your switch
statements. Below is a variation of our example that will result in none of the cases
being used causing our switch statement to fall back and use the default case. Note: the word
case does not appear before the word default, as default is a special keyword!
Using PHP With HTML Forms
It is time to apply the knowledge you have obtained thus far and put it to real use. A very common application of PHP is to have an HTML form gather information from a website's visitor and then use PHP to do process that information. In this lesson we will simulate a small business's website that is implementing a very simple order form.
Imagine we are an art supply store that
sells brushes, paint, and erasers. To gather order information
from our prospective customers we will have to make a page with an HTML form
to gather the customer's order.
Note: This is an oversimplified example to educate you how to
use PHP to process HTML form information. This example
is not intended nor advised to be used on a real business website.
check out the HTML Form
Lesson before continuing on.
We first create an HTML form that will let our customer choose
what they would like to purchase. This file should be saved
as "order.html"
.
Remember to review HTML Forms
if you do not understand any of the above HTML code. Next we must alter
our HTML form to specify the PHP page we wish to send this information to. Also,
we set the method to "post".
Now that our "order.html" is complete, let us continue on and
create the "process.php" file which will process the HTML form information.
in our HTML form. Using an associative array (this term is explained in the array lesson),
we can get this information from the $_POST associative array.
The proper way to get this information would be to create two new variables, $item
and $quantity and set them equal to the values that have been "posted". The name
of this file is "process.php".
As you probably noticed, the name in $_POST['name'] corresponds
to the name that we specified in our HTML form.
Now try uploading the "order.html" and "process.php" files to a PHP
enabled server and test them out. If someone selected the item brushes
and specified a quantity of 6, then the following
would be displayed on "process.php":
it to be sure you understand what was going on.
Remember, this lesson is only to teach you how to use PHP to get information
from HTML forms. The example on this page should not be used for a real business.
In the previous lessons we covered the various elements that make up an If Statement in PHP. However, there are times when an if statement is not the most efficient way to check for certain conditions.
For example we might have a variable that stores travel destinations and you want
to pack according to this destination variable. In this example you might have
20 different locations that you would have to check with a nasty long block
of If/ElseIf/ElseIf/ElseIf/... statements. This doesn't sound like much fun to code,
let's see if we can do something different.
PHP Switch Statement: Speedy Checking
With the use of the switch statement you can check for all theseconditions at once, and the great thing is that it is actually more efficient
programming to do this. A true win-win situation!
The way the Switch statement works is it takes a single variable as input
and then checks it against all the different cases you set up for that
switch statement. Instead of having to check that variable one at a time,
as it goes through a bunch of If Statements, the Switch statement only has to check
one time.
PHP Switch Statement Example
In our example the single variable will be $destination
and the cases will be: Las Vegas, Amsterdam, Egypt, Tokyo, and the Caribbean Islands.
PHP Code:
$destination = "Tokyo"; echo "Traveling to $destination<br />"; switch ($destination){ case "Las Vegas": echo "Bring an extra $500"; break; case "Amsterdam": echo "Bring an open mind"; break; case "Egypt": echo "Bring 15 bottles of SPF 50 Sunscreen"; break; case "Tokyo": echo "Bring lots of money"; break; case "Caribbean Islands": echo "Bring a swimsuit"; break; }
Display:
Traveling to Tokyo
Bring lots of money
The value of $destination was Tokyo, so when PHP performed the switchBring lots of money
operating on $destination in immediately did a search for a case with the
value of "Tokyo". It found it and proceeded to execute the code that existed
within that segment.
You might have noticed how each case contains a break; at the end of its code area. This
break prevents the other cases from being executed. If the above example did not
have any break statements then all the cases that follow Tokyo would have been executed as well.
Use this knowledge to enhance the power of your switch statements!
The form of the switch statement is rather unique, so spend some time reviewing it
before moving on. Note: Beginning programmers should always include the break; to
avoid any unnecessary confusion.
PHP Switch Statement: Default Case
You may have noticed the lack of a place for code when thevariable doesn't match our condition. The if statement has the else clause and
the switch statement has the default case.
It's usually a good idea to always include the default case in all your switch
statements. Below is a variation of our example that will result in none of the cases
being used causing our switch statement to fall back and use the default case. Note: the word
case does not appear before the word default, as default is a special keyword!
PHP Code:
$destination = "New York"; echo "Traveling to $destination<br />"; switch ($destination){ case "Las Vegas": echo "Bring an extra $500"; break; case "Amsterdam": echo "Bring an open mind"; break; case "Egypt": echo "Bring 15 bottles of SPF 50 Sunscreen"; break; case "Tokyo": echo "Bring lots of money"; break; case "Caribbean Islands": echo "Bring a swimsuit"; break; default: echo "Bring lots of underwear!"; break; }
Display:
Traveling to New York
Bring lots of underwear!
Bring lots of underwear!

Creating the HTML Form
If you need a refresher on how to properly make an HTML form,check out the HTML Form
Lesson before continuing on.
We first create an HTML form that will let our customer choose
what they would like to purchase. This file should be saved
as "order.html"
.
order.html Code:
<html><body> <h4>Tizag Art Supply Order Form</h4> <form> <select> <option>Paint</option> <option>Brushes</option> <option>Erasers</option> </select> Quantity: <input type="text" /> <input type="submit" /> </form> </body></html>
Display:
Tizag Art Supply Order Form
Remember to review HTML Forms
if you do not understand any of the above HTML code. Next we must alter
our HTML form to specify the PHP page we wish to send this information to. Also,
we set the method to "post".
order.html Code:
<html><body> <h4>Tizag Art Supply Order Form</h4> <form action="process.php" method="post"> <select name="item"> <option>Paint</option> <option>Brushes</option> <option>Erasers</option> </select> Quantity: <input name="quantity" type="text" /> <input type="submit" /> </form> </body></html>
Now that our "order.html" is complete, let us continue on and
create the "process.php" file which will process the HTML form information.
PHP Form Processor
We want to get the "item" and "quantity" inputs that we have specifiedin our HTML form. Using an associative array (this term is explained in the array lesson),
we can get this information from the $_POST associative array.
The proper way to get this information would be to create two new variables, $item
and $quantity and set them equal to the values that have been "posted". The name
of this file is "process.php".
process.php Code:
<html><body> <?php $quantity = $_POST['quantity']; $item = $_POST['item']; echo "You ordered ". $quantity . " " . $item . ".<br />"; echo "Thank you for ordering from Tizag Art Supplies!"; ?> </body></html>
As you probably noticed, the name in $_POST['name'] corresponds
to the name that we specified in our HTML form.
Now try uploading the "order.html" and "process.php" files to a PHP
enabled server and test them out. If someone selected the item brushes
and specified a quantity of 6, then the following
would be displayed on "process.php":
process.php Code:
You ordered 6 brushes. Thank you for ordering from Tizag Art Supplies!
PHP & HTML Form Review
A lot of things were going on in this example. Let us step throughit to be sure you understand what was going on.
- We first created an HTML form "order.html" that had two input fields
specified, "item" and "quantity". - We added two attributes to the form tag to point to "process.php" and
set the method to "post". - We had "process.php" get the information that was posted
by setting new variables equal to the values in the $_POST associative array. - We used the PHP echo function to output the customers order.
Remember, this lesson is only to teach you how to use PHP to get information
from HTML forms. The example on this page should not be used for a real business.
The If Statement in PHP
The If Statement
The PHP if statement is very similar to other programming languages use of the if statement, but for those who are not familiar with it, picture the following:
Think about the decisions you make before you go to sleep. If you have
something to do the next day, say go to work, school, or an appointment, then
you will set your alarm clock to wake you up. Otherwise, you will sleep in as
long as you like!
This simple kind of if/then statement is very common in every day life and
also appears in programming quite often. Whenever you want to make a decision
given that something is true (you have something to do tomorrow) and be sure that you
take the appropriate action, you are using an if/then relationship.
1st you want to print out "Happy New Year!" at the top of your personal web page. With the use of PHP if statements you could have this process automated,
months in advance, occuring every year on January 1st.
This idea of planning for future
events is something you would never have had the opportunity of doing if you
had just stuck with HTML.
to do right now, so let us instead start off with the basics of the if statement.
The PHP if statement tests to see if a value is true, and if it is a segment of
code will be executed. See the example below for the form of a PHP if statement.
were equal? In PHP you use the double equal sign (==) to compare values.
Additionally, notice that because the if statement turned out to be true, the code segment
was executed, printing out "Your name is someguy!". Let's go a bit more in-depth into this example
to iron out the details.
other words, false. Say that we changed the above example to:
Here the variable contained the value "anotherguy", which is not equal to "someguy".
The if statement evaluated to false, so the code segment of the if statement was not
executed. When used properly, the if statement is a powerful tool to have in your
programming arsenal!
If/Else Conditional Statment
Has someone ever told you, "if you work hard, then you will succeed"? And what happens if you do not work hard? Well, you fail! This is an example of an if/else conditional statement.
If you work hard then you will succeed.
Else, if you do not work hard, then you will fail.
How does this translate into something useful for PHP developers?
Well consider this:
Someone comes to your website and you want to ask
this visitor her name if it is her first time coming to your site. With an if statement
this is easy. Simply have a conditional statement to check, "are
you visiting for the first time". If the condition is true, then take them to
the "Insert Your Name" page, else let her view the website as normal because you have already asked her for her name
in the past.
website. Here's the basic form of an if/else statement in PHP.
code, line by line.
executed. Note that the code within the if and else cannot both be executed, as
the if statement cannot evaluate to both true and false at one time! Here is what would happen
if we changed to $number_three to anything besides the number 3.
the code segment contained within the else was used in this case.
PHP - Elseif
An if/else statement is great if you only need to check for one condition. However, what would you do if you wanted to check if your $employee variable was the company owner Bob, the Vice President Ms. Tanner, or a regular employee? To check for these different conditions you would need the elseif statement.
Just like an if statement, an elseif statement also contains a conditional statement, but it must be preceded
by an if statement. You cannot have an elseif statement without first having an if statement.
When PHP evaluates your If...elseif...else statement it will first see if the If statement is true. If that
tests comes out false it will then check the first elseif statement. If that is false it will either check the next
elseif statement, or if there are no more elseif statements, it will evaluate the else segment, if one exists (I don't
think I've ever used the word "if" so much in my entire life!). Let's take a look at a real world example.
We simply want
to find out if the employee is the Vice President Ms. Tanner. We only need an if else statement for
this part of the example.
Now, if we wanted to also check to see if the big boss Bob was the employee we need
to insert an elseif clause.
PHP first checked to see if $employee was equal to "Ms. Tanner", which evaluated to
false. Next, PHP checked the first elseif statement. $employee did in
fact equal "Bob" so the phrase "Good Morning Sir!" was printed out. If we wanted
to check for more employee names we could insert more elseif statements!
Remember that an elseif statement cannot be used unless it is preceded
by an if statement!
The PHP if statement is very similar to other programming languages use of the if statement, but for those who are not familiar with it, picture the following:
Think about the decisions you make before you go to sleep. If you have
something to do the next day, say go to work, school, or an appointment, then
you will set your alarm clock to wake you up. Otherwise, you will sleep in as

also appears in programming quite often. Whenever you want to make a decision
given that something is true (you have something to do tomorrow) and be sure that you
take the appropriate action, you are using an if/then relationship.
The PHP If Statement
The if statement is necessary for most programming, thus it is important in PHP. Imagine that on January1st you want to print out "Happy New Year!" at the top of your personal web page. With the use of PHP if statements you could have this process automated,
months in advance, occuring every year on January 1st.
This idea of planning for future
events is something you would never have had the opportunity of doing if you
had just stuck with HTML.
If Statement Example
The "Happy New Year" example would be a little difficult for youto do right now, so let us instead start off with the basics of the if statement.
The PHP if statement tests to see if a value is true, and if it is a segment of
code will be executed. See the example below for the form of a PHP if statement.
PHP Code:
$my_name = "someguy"; if ( $my_name == "someguy" ) { echo "Your name is someguy!<br />"; } echo "Welcome to my homepage!";
Display:
Your name is someguy!
Welcome to my homepage!
Did you get that we were comparing the variable $my_name with "someguy" to see if theyWelcome to my homepage!
were equal? In PHP you use the double equal sign (==) to compare values.
Additionally, notice that because the if statement turned out to be true, the code segment
was executed, printing out "Your name is someguy!". Let's go a bit more in-depth into this example
to iron out the details.
- We first set the variable $my_name equal to "someguy".
- We next used a PHP if statement to check if the value contained in the
variable $my_name was equal to "someguy" - The comparison between $my_name and "someguy" was done with a double equal
sign "==", not a single equals"="! A single equals is for assigning a value
to a variable, while a double equals is for checking if things are equal. - Translated into english the PHP statement ( $my_name == "someguy" ) is ( $my_name
is equal to "someguy" ). - $my_name is indeed equal to "someguy" so the echo statement is executed.
A False If Statement
Let us now see what happens when a PHP if statement is not true, inother words, false. Say that we changed the above example to:
PHP Code:
$my_name = "anotherguy"; if ( $my_name == "someguy" ) { echo "Your name is someguy!<br />"; } echo "Welcome to my homepage!";
Display:
Welcome to my homepage!
Here the variable contained the value "anotherguy", which is not equal to "someguy".
The if statement evaluated to false, so the code segment of the if statement was not
executed. When used properly, the if statement is a powerful tool to have in your
programming arsenal!
If/Else Conditional Statment
Has someone ever told you, "if you work hard, then you will succeed"? And what happens if you do not work hard? Well, you fail! This is an example of an if/else conditional statement.
How does this translate into something useful for PHP developers?
Well consider this:
Someone comes to your website and you want to ask
this visitor her name if it is her first time coming to your site. With an if statement
this is easy. Simply have a conditional statement to check, "are
you visiting for the first time". If the condition is true, then take them to
the "Insert Your Name" page, else let her view the website as normal because you have already asked her for her name
in the past.
If/Else an Example
Using these conditional statements can add a new layers of "cool" to yourwebsite. Here's the basic form of an if/else statement in PHP.
PHP Code:
$number_three = 3; if ( $number_three == 3 ) { echo "The if statement evaluated to true"; } else { echo "The if statement evaluated to false"; }
Display:
The if statement evaluated to true
This is a lot to digest in one sitting, so let us step through thecode, line by line.
- We first made a PHP variable called $number_three and set it equal to 3.
- In this example we compared a variable to
an integer value. To do such a comparison we use "==", which in English means "Is Equal To". - $number_three is indeed Equal To 3 and so this statement will evaluate to true.
- All code that is contained between the opening curly brace "{" that follows the if
statement and the closing curly brace "}" will be executed when the if statement is true. - The code contained within the else segment will not used.
Execute Else Code with False
On the other hand, if the if statement was false, then the code contained in the else segment would have beenexecuted. Note that the code within the if and else cannot both be executed, as
the if statement cannot evaluate to both true and false at one time! Here is what would happen
if we changed to $number_three to anything besides the number 3.
PHP Code:
$number_three = 421; if ( $number_three == 3 ) { echo "The if statement evaluated to true"; } else { echo "The if statement evaluated to false"; }
Display:
The if statement evaluated to false
The variable was set to 421, which is not equal to 3 and the if statement was false. As you can see,the code segment contained within the else was used in this case.
PHP - Elseif
An if/else statement is great if you only need to check for one condition. However, what would you do if you wanted to check if your $employee variable was the company owner Bob, the Vice President Ms. Tanner, or a regular employee? To check for these different conditions you would need the elseif statement.
PHP - Elseif What is it?
An if statement is made up of the keyword "if" and a conditional statement (i.e. $name == "Ted").Just like an if statement, an elseif statement also contains a conditional statement, but it must be preceded
by an if statement. You cannot have an elseif statement without first having an if statement.
When PHP evaluates your If...elseif...else statement it will first see if the If statement is true. If that
tests comes out false it will then check the first elseif statement. If that is false it will either check the next
elseif statement, or if there are no more elseif statements, it will evaluate the else segment, if one exists (I don't
think I've ever used the word "if" so much in my entire life!). Let's take a look at a real world example.
PHP - Using Elseif with If...Else
Let's start out with the base case. Imagine we have a simpler version of the problem described above.We simply want
to find out if the employee is the Vice President Ms. Tanner. We only need an if else statement for
this part of the example.
PHP Code:
$employee = "Bob"; if($employee == "Ms. Tanner"){ echo "Hello Ma'am"; } else { echo "Morning"; }
to insert an elseif clause.
PHP Code:
$employee = "Bob"; if($employee == "Ms. Tanner"){ echo "Hello Ma'am"; } elseif($employee == "Bob"){ echo "Good Morning Sir!"; }else { echo "Morning"; }
Display:
Good Morning Sir!
PHP first checked to see if $employee was equal to "Ms. Tanner", which evaluated to
false. Next, PHP checked the first elseif statement. $employee did in
fact equal "Bob" so the phrase "Good Morning Sir!" was printed out. If we wanted
to check for more employee names we could insert more elseif statements!
Remember that an elseif statement cannot be used unless it is preceded
by an if statement!
PHP - Operators
PHP - Operators
In all programming languages, operators are used to manipulate or perform operations on variables and values. You have already seen the string concatenation operator "." in the Echo Lesson and the assignment operator "=" in pretty much every PHP example so far.
There are many operators used in PHP, so we have separated them into
the following categories to make it easier to learn them all.
a variable to another variable's value. Such an assignment of value is done with
the "=", or equal character. Example:
values. If you would like to see a simple example of a comparison operator in action, check out our
If Statement Lesson. Comparison
operators are used inside conditional statements and evaluate to either true
or false. Here are the most important comparison operators of PHP.
Assume: $x = 4 and $y = 5;
Lesson, the period "." is used to add two strings together, or more technically,
the period is the concatenation operator for strings.
most common example of this is a counter. Say you want to increment a counter by 1, you would
have:
combination operator is that it reduces code readability to those programmers who are not used to such
an operator. Here are some examples of other common
shorthand operators. In general, "+=" and "-=" are the most widely used combination operators.
task of adding 1 or subtracting 1 from a variable. To add one to a variable or "increment"
use the "++" operator:
want to increment before the line of code is being executed or after the
line has executed. Our PHP code below will display the difference.
the variable is not incremented until after the line of code is executed. However,
with the pre-increment "++$x" the variable does reflect the addition immediately.
Using Comments in PHP
Comments in PHP are similar to comments that are used in HTML. The PHP comment syntax always begins with a special character sequence and all text that appears between the start of the comment and the end will be ignored.
In HTML a comment's main purpose is to serve as a note to you, the web developer or to others who may view your website's source code. However, PHP's comments are different in that they will not be displayed to your visitors. The only way to view PHP comments is to open the PHP file for editing. This makes PHP comments only useful to PHP programmers.
In case you forgot what an HTML comment looked like, see our example below.
commented them out with the single line comment.
This type of line commenting is often used for quick notes about
complex and confusing code or to temporarily remove a line of PHP code.
can be used to comment out large blocks of code or writing multiple
line comments. The multiple line PHP comment begins with " /* " and ends
with " */ ".
new PHP programmers is....USE THEM!! So many people write complex
PHP code and are either too lazy to write good comments or believe
the commenting is not needed. However, do you really believe that you
will remember exactly what you were thinking when looking at this code
a year or more down the road?
Let the comments permeate your code and you will be a happier PHPer
in the future. Use single line comments for quick notes about a tricky
part in your code and use multiple line comments when you need to describe
something in greater depth than a simple note.
PHP Include
Without understanding much about the details of PHP, you can save yourself a great deal of time with the use of the PHP include command. include takes a file name and simply inserts that file's contents into the script that issued the include command.
Why is this a cool thing? Well, first of all, this means that you can type up a common header or menu file that you want all your web pages to include. When you add a new page to your site, instead of having to update the links on several web pages, you can simply change the Menu file.
will use. A common practice for naming files that are to be included is to use the ".php" extension. Since we want to create a common menu
let's save it as "menu.php".
Save the above file as "menu.php". Now create a new file, "index.php" in the same directory as
"menu.php". Here we will take advantage of the include command to add our common menu.
how terrible it would be if you had 15 or more pages with a common menu and you decided to add
another web page to that site. You would have to go in and manually edit every single file to add this
new page, but with include files you simply have to change "menu.php" and all your problems are solved.
Avoid such troublesome occasions with a simple include file.
would the visitor see if they viewed the source of "index.php"? Well, because the include command
is pretty much the same as copying and pasting, the visitors would see:
The visitor would actually see all the HTML code as one long line of HTML code, because
we have not inserted any new line characters. We did some formatting above to make it easier to read. We will be discussing new line characters later.
it into the file that uses the include command. Include is quite useful when you want to include the same PHP, HTML, or text segment on multiple pages of a website. The include command is used widely by PHP web developers. Like PHP Echo, include is not a function, but a language construct.
The next lesson will talk about a slight variation of the include command: require. It is often best to use the require command instead of the include command in your PHP Code. Read the next lesson to find out why!
PHP Require
Just like the previous lesson, the require command is used to include a file into your PHP code. However there is one huge difference between the two commands, though it might not seem that big of a deal.
find it you will see an error message like the following:
Notice that our echo statement is still executed, this is because a Warning does not prevent our PHP script from running.
On the other hand, if we did the same example but used the require statement we would get something like the following example.
The echo statement was not executed because our script execution died after the require command returned a fatal error! We recommend that you use require instead of include because your scripts should not be executing if necessary files are missing or misnamed.
In all programming languages, operators are used to manipulate or perform operations on variables and values. You have already seen the string concatenation operator "." in the Echo Lesson and the assignment operator "=" in pretty much every PHP example so far.
There are many operators used in PHP, so we have separated them into
the following categories to make it easier to learn them all.
- Assignment Operators
- Arithmetic Operators
- Comparison Operators
- String Operators
- Combination Arithmetic & Assignment Operators
Assignment Operators
Assignment operators are used to set a variable equal to a value or seta variable to another variable's value. Such an assignment of value is done with
the "=", or equal character. Example:
- $my_var = 4;
- $another_var = $my_var;
Arithmetic Operators
Operator | English | Example |
---|---|---|
+ | Addition | 2 + 4 |
- | Subtraction | 6 - 2 |
* | Multiplication | 5 * 3 |
/ | Division | 15 / 3 |
% | Modulus | 43 % 10 |
PHP Code:
$addition = 2 + 4; $subtraction = 6 - 2; $multiplication = 5 * 3; $division = 15 / 3; $modulus = 5 % 2; echo "Perform addition: 2 + 4 = ".$addition."<br />"; echo "Perform subtraction: 6 - 2 = ".$subtraction."<br />"; echo "Perform multiplication: 5 * 3 = ".$multiplication."<br />"; echo "Perform division: 15 / 3 = ".$division."<br />"; echo "Perform modulus: 5 % 2 = " . $modulus . ". Modulus is the remainder after the division operation has been performed. In this case it was 5 / 2, which has a remainder of 1.";
Display:
Perform addition: 2 + 4 = 6
Perform subtraction: 6 - 2 = 4
Perform multiplication: 5 * 3 = 15
Perform division: 15 / 3 = 5
Perform modulus: 5 % 2 = 1. Modulus is the remainder after the division operation has been performed.
In this case it was 5 / 2, which has a remainder of 1.
Perform subtraction: 6 - 2 = 4
Perform multiplication: 5 * 3 = 15
Perform division: 15 / 3 = 5
Perform modulus: 5 % 2 = 1. Modulus is the remainder after the division operation has been performed.
In this case it was 5 / 2, which has a remainder of 1.
Comparison Operators
Comparisons are used to check the relationship between variables and/orvalues. If you would like to see a simple example of a comparison operator in action, check out our
If Statement Lesson. Comparison
operators are used inside conditional statements and evaluate to either true
or false. Here are the most important comparison operators of PHP.
Assume: $x = 4 and $y = 5;
Operator | English | Example | Result |
---|---|---|---|
== | Equal To | $x == $y | false |
!= | Not Equal To | $x != $y | true |
< | Less Than | $x < $y | true |
> | Greater Than | $x > $y | false |
<= | Less Than or Equal To | $x <= $y | true |
>= | Greater Than or Equal To | $x >= $y | false |
String Operators
As we have already seen in the EchoLesson, the period "." is used to add two strings together, or more technically,
the period is the concatenation operator for strings.
PHP Code:
$a_string = "Hello"; $another_string = " Billy"; $new_string = $a_string . $another_string; echo $new_string . "!";
Display:
Hello Billy!
Combination Arithmetic & Assignment Operators
In programming it is a very common task to have to increment a variable by some fixed amount. Themost common example of this is a counter. Say you want to increment a counter by 1, you would
have:
- $counter = $counter + 1;
- $counter += 1;
combination operator is that it reduces code readability to those programmers who are not used to such
an operator. Here are some examples of other common
shorthand operators. In general, "+=" and "-=" are the most widely used combination operators.
Operator | English | Example | Equivalent Operation |
---|---|---|---|
+= | Plus Equals | $x += 2; | $x = $x + 2; |
-= | Minus Equals | $x -= 4; | $x = $x - 4; |
*= | Multiply Equals | $x *= 3; | $x = $x * 3; |
/= | Divide Equals | $x /= 2; | $x = $x / 2; |
%= | Modulo Equals | $x %= 5; | $x = $x % 5; |
.= | Concatenate Equals | $my_str.="hello"; | $my_str = $my_str . "hello"; |
Pre/Post-Increment & Pre/Post-Decrement
This may seem a bit absurd, but there is even a shorter shorthand for the commontask of adding 1 or subtracting 1 from a variable. To add one to a variable or "increment"
use the "++" operator:
- $x++; Which is equivalent to $x += 1; or $x = $x + 1;
- $x--; Which is equivalent to $x -= 1; or $x = $x - 1;
want to increment before the line of code is being executed or after the
line has executed. Our PHP code below will display the difference.
PHP Code:
$x = 4; echo "The value of x with post-plusplus = " . $x++; echo "<br /> The value of x after the post-plusplus is " . $x; $x = 4; echo "<br />The value of x with with pre-plusplus = " . ++$x; echo "<br /> The value of x after the pre-plusplus is " . $x;
Display:
The value of x with post-plusplus = 4
The value of x after the post-plusplus is = 5
The value of x with with pre-plusplus = 5
The value of x after the pre-plusplus is = 5
As you can see the value of $x++ is not reflected in the echoed text because The value of x after the post-plusplus is = 5
The value of x with with pre-plusplus = 5
The value of x after the pre-plusplus is = 5
the variable is not incremented until after the line of code is executed. However,
with the pre-increment "++$x" the variable does reflect the addition immediately.
Using Comments in PHP
Comments in PHP are similar to comments that are used in HTML. The PHP comment syntax always begins with a special character sequence and all text that appears between the start of the comment and the end will be ignored.
In HTML a comment's main purpose is to serve as a note to you, the web developer or to others who may view your website's source code. However, PHP's comments are different in that they will not be displayed to your visitors. The only way to view PHP comments is to open the PHP file for editing. This makes PHP comments only useful to PHP programmers.
In case you forgot what an HTML comment looked like, see our example below.
HTML Code:
<!-- This is an HTML Comment -->
PHP Comment Syntax: Single Line Comment
While there is only one type of comment in HTML, PHP has two types. The first type we will discuss is the single line comment. The single line comment tells the interpreter to ignore everything that occurs on that line to the right of the comment. To do a single line comment type "//" or "#" and all text to the right will be ignored by PHP interpreter.PHP Code:
<?php echo "Hello World!"; // This will print out Hello World! echo "<br />Psst...You can't see my PHP comments!"; // echo "nothing"; // echo "My name is Humperdinkle!"; # echo "I don't do anything either"; ?>
Display:
Hello World!
Psst...You can't see my PHP comments!
Notice that a couple of our echo statements were not evaluated because wePsst...You can't see my PHP comments!
commented them out with the single line comment.
This type of line commenting is often used for quick notes about
complex and confusing code or to temporarily remove a line of PHP code.
PHP Comment Syntax: Multiple Line Comment
Similiar to the HTML comment, the multi-line PHP commentcan be used to comment out large blocks of code or writing multiple
line comments. The multiple line PHP comment begins with " /* " and ends
with " */ ".
PHP Code:
<?php /* This Echo statement will print out my message to the the place in which I reside on. In other words, the World. */ echo "Hello World!"; /* echo "My name is Humperdinkle!"; echo "No way! My name is Uber PHP Programmer!"; */ ?>
Display:
Hello World!
Good Commenting Practices
One of the best commenting practices that I can recommend tonew PHP programmers is....USE THEM!! So many people write complex
PHP code and are either too lazy to write good comments or believe
the commenting is not needed. However, do you really believe that you
will remember exactly what you were thinking when looking at this code
a year or more down the road?
Let the comments permeate your code and you will be a happier PHPer
in the future. Use single line comments for quick notes about a tricky
part in your code and use multiple line comments when you need to describe
something in greater depth than a simple note.
PHP Include
Without understanding much about the details of PHP, you can save yourself a great deal of time with the use of the PHP include command. include takes a file name and simply inserts that file's contents into the script that issued the include command.
Why is this a cool thing? Well, first of all, this means that you can type up a common header or menu file that you want all your web pages to include. When you add a new page to your site, instead of having to update the links on several web pages, you can simply change the Menu file.
An Include Example
Say we wanted to create a common menu file that all our pageswill use. A common practice for naming files that are to be included is to use the ".php" extension. Since we want to create a common menu
let's save it as "menu.php".
menu.php Code:
<html> <body> <a href="http://www.example.com/index.php">Home</a> - <a href="http://www.example.com/about.php">About Us</a> - <a href="http://www.example.com/links.php">Links</a> - <a href="http://www.example.com/contact.php">Contact Us</a> <br />
Save the above file as "menu.php". Now create a new file, "index.php" in the same directory as
"menu.php". Here we will take advantage of the include command to add our common menu.
index.php Code:
<?php include("menu.php"); ?> <p>This is my home page that uses a common menu to save me time when I add new pages to my website!</p> </body> </html>
Display:
Home -
About Us -
Links -
Contact Us
This is my home page that uses a common menu to save me time when I add new pages to my website!
And we would do the same thing for "about.php", "links.php", and "contact.php". Just thinkAbout Us -
Links -
Contact Us
This is my home page that uses a common menu to save me time when I add new pages to my website!
how terrible it would be if you had 15 or more pages with a common menu and you decided to add
another web page to that site. You would have to go in and manually edit every single file to add this
new page, but with include files you simply have to change "menu.php" and all your problems are solved.
Avoid such troublesome occasions with a simple include file.
What do Visitors See?
If we were to use the include command to insert a menu on each of our web pages, whatwould the visitor see if they viewed the source of "index.php"? Well, because the include command
is pretty much the same as copying and pasting, the visitors would see:
View Source of index.php to a Visitor:
<html> <body> <a href="index.php">Home</a> - <a href="about.php">About Us</a> - <a href="links.php">Links</a> - <a href="contact.php">Contact Us</a> <br /> <p>This is my home page that uses a common menu to save me time when I add new pages to my website!</p> </body> </html>
The visitor would actually see all the HTML code as one long line of HTML code, because
we have not inserted any new line characters. We did some formatting above to make it easier to read. We will be discussing new line characters later.
Include Recap
The include command simply takes all the text that exists in the specified file and copiesit into the file that uses the include command. Include is quite useful when you want to include the same PHP, HTML, or text segment on multiple pages of a website. The include command is used widely by PHP web developers. Like PHP Echo, include is not a function, but a language construct.
The next lesson will talk about a slight variation of the include command: require. It is often best to use the require command instead of the include command in your PHP Code. Read the next lesson to find out why!
PHP Require
Just like the previous lesson, the require command is used to include a file into your PHP code. However there is one huge difference between the two commands, though it might not seem that big of a deal.
Require vs Include
When you include a file with the include command and PHP cannotfind it you will see an error message like the following:
PHP Code:
<?php include("noFileExistsHere.php"); echo "Hello World!"; ?>
Display:
Warning: main(noFileExistsHere.php): failed to open stream: No such file or directory in /home/websiteName/FolderName/tizagScript.php on line 2
Warning: main(): Failed opening 'noFileExistsHere.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/websiteName/FolderName/tizagScript.php on line 2
Hello World!
Warning: main(): Failed opening 'noFileExistsHere.php' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/websiteName/FolderName/tizagScript.php on line 2
Hello World!
Notice that our echo statement is still executed, this is because a Warning does not prevent our PHP script from running.
On the other hand, if we did the same example but used the require statement we would get something like the following example.
PHP Code:
<?php require("noFileExistsHere.php"); echo "Hello World!"; ?>
Display:
Warning: main(noFileExistsHere.php): failed to open stream: No such file or directory in /home/websiteName/FolderName/tizagScript.php on line 2
Fatal error: main(): Failed opening required 'noFileExistsHere.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/websiteName/FolderName/tizagScript.php on line 2
Fatal error: main(): Failed opening required 'noFileExistsHere.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/websiteName/FolderName/tizagScript.php on line 2
The echo statement was not executed because our script execution died after the require command returned a fatal error! We recommend that you use require instead of include because your scripts should not be executing if necessary files are missing or misnamed.
