$_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)
