(PHP 4 >= 4.1.0, PHP 5)

$_GET -- $HTTP_GET_VARS [deprecated] — HTTP GET variables

### Description

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)

### Changelog

Version | Description
--- | ---
4.1.0 | Introduced $_GET that deprecated $HTTP_GET_VARS.

### 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().
