[FONT=Verdana][SIZE=2][COLOR=Black]Hi,[/COLOR][/SIZE][/FONT]  
[FONT=Verdana][SIZE=2][/SIZE][/FONT]  
[FONT=Verdana][SIZE=2][COLOR=Black]This is mostly a post out of curiosity…[/COLOR][/SIZE][/FONT]  
[FONT=Verdana][SIZE=2][/SIZE][/FONT]  
[FONT=Verdana][SIZE=2][COLOR=Black]I know when the URL of a website is something like: [www.somesite.com/file.php?a=hello](http://www.somesite.com/file.php?a=hello)[/COLOR][/SIZE][/FONT]  
[FONT=Verdana][SIZE=2][/SIZE][/FONT]  
[FONT=Verdana][SIZE=2][COLOR=Black]The variable a is set to “hello”[/COLOR][/SIZE][/FONT]

Example code:

```php
if (isset($_GET['a'])) {
$a = $_GET['a']; }

```

[FONT=Verdana][SIZE=2][COLOR=Black][/COLOR][/SIZE][/FONT]  
So now $a would now be, “hello”.  
[FONT=Verdana][SIZE=2][COLOR=Black][/COLOR][/SIZE][/FONT]  
[FONT=Verdana][SIZE=2][COLOR=Black]  
[/COLOR][/SIZE][/FONT]  
[FONT=Verdana][SIZE=2][COLOR=Black]But I have seem some sites that use [www.somesite.com/file.php?home](http://www.somesite.com/file.php?home) or /file.php?contact[/COLOR][/SIZE][/FONT]  
[FONT=Verdana][SIZE=2][COLOR=Black] [/COLOR][/SIZE][/FONT]  
[FONT=Verdana][SIZE=2][COLOR=Black]What exactly is this? Is it setting a blank variable “home” / “contact” or is it telling the file.php to execute the function “home” / “contact”.[/COLOR][/SIZE][/FONT]  
[FONT=Verdana][SIZE=2][COLOR=Black] [/COLOR][/SIZE][/FONT]  
[FONT=Verdana][SIZE=2][COLOR=Black]Just wondering.[/COLOR][/SIZE][/FONT]  
[FONT=Verdana][SIZE=2][COLOR=Black] [/COLOR][/SIZE][/FONT]  
[FONT=Verdana][SIZE=2][COLOR=Black]Thanks![/COLOR][/SIZE][/FONT]
