$_POST - HTTP POST variables
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 vari-
ables and that PHP handles them as such)

|Version | |

| | |
+--------+---------------------------------------------------+
| 4.1.0 | |
| | |
| | Introduced $_POST that deprecated |
| | $HTTP_POST_VARS. |

+--------+---------------------------------------------------+
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!
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
When running on the command line , this will not include the argv and argc entries; these are present in the $_SERVER array.
Note
The variables in $_REQUEST are provided to the script via the GET, POST, and COOKIE input mechanisms and therefore could be modi-
fied by the remote user and cannot be trusted. The presence and order of variables listed in this array is defined according to the
PHP variables_order configuration directive.
