$_GET

$HTTP_GET_VARS [deprecated]

(No version information available, might be only in CVS)

$HTTP_GET_VARS [deprecated] — HTTP GET variables

Description

An associative array of variables passed to the current script via the HTTP GET method.

$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 that named anchors are not part of the query string and are never submitted by the browser to the server.



Eg.

http://www.xyz-abc.kz/index.php?title=apocalypse.php#doom



echo $_GET['title']; 



// returns "apocalypse.php" and NOT "apocalypse.php#doom"



you would be better off treating the named anchor as another query string variable like so:

http://www.xyz-abc.kz/index.php?title=apocalypse.php&na=doom



...and then retrieve it using something like this:

$url = $_GET['title']."#".$_GET['na'];



Hope this helps someone...

If nothing is set in the address bar, the value of $_GET['n'] will be NULL, not ""(empty string) or false.
