via the HTTP POST method when using application/x-www-form-urlencoded
or multipart/form-data as the HTTP Content-Type in the request.

?>

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.
Note:
To read POST data sent with other content types (e.g.
application/json or application/xml)
php://input
must be used. Unlike $_POST, which only works with
application/x-www-form-urlencoded and
multipart/form-data, php://input
provides direct access to the raw data from the body of the request.
