$_GET - HTTP GET variables
An associative array of variables passed to the current script via the URL parameters.
$HTTP_GET_VARS contains the same initial information, but is not a superglobal. (Note that $HTTP_GET_VARS and $_GET are different variables
and that PHP handles them as such)

$_GET example
<?php
echo 'Hello ' . htmlspecialchars($_GET["name"]) . '!';
?>
Assuming the user entered http://example.com/?name=Hannes
The above example will output something similar to:
Hello Hannes!
Note
This is a 'superglobal', or automatic global, variable. This simply means that it is available in all scopes throughout a script.
There is no need to do global $variable; to access it within functions or methods.
Note
The GET variables are passed through urldecode(3).
Handling external variables, The filter extension.
