$_POST
$HTTP_POST_VARS [deprecated]
(PHP 4 >= 4.1.0, PHP 5, PHP 7)
$_POST -- $HTTP_POST_VARS [deprecated] — HTTP POST variables
Description
An associative array of variables passed to the current script via the HTTP POST method when using application/x-www-form-urlencoded or multipart/form-data as the HTTP Content-Type in the request.
$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)
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.
