HTTP POST variables


$_POST

$HTTP_POST_VARS [deprecated]

(PHP 4 >= 4.1.0, PHP 5)

$_POST -- $HTTP_POST_VARS [deprecated]HTTP POST variables

Description

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

$HTTP_POST_VARS contains the same initial information, but is not a superglobal. (Note that $HTTP_POST_VARS and $_POST are different variables and that PHP handles them as such)

Changelog

Version Description
4.1.0 Introduced $_POST that deprecated $HTTP_POST_VARS.

Examples

Example #1 $_POST example

<?php
echo 'Hello ' htmlspecialchars($_POST["name"]) . '!';
?>

Assuming the user POSTed 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.
