$_GET — HTTP GET variables

### Description

An associative array of variables passed to the current script via the URL parameters (aka. query string). Note that the array is not only populated for GET requests, but rather for all requests with a query string.

### Examples

Example #1 $_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!

### Notes

> 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().
