$_GET

$HTTP_GET_VARS [deprecated]

$_GET -- $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.


Use this code if you want to retrieve your queries no matter what method is used. Hope it helps.

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...

Note:

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

add a note

$_POST

$_SERVER
