Which PHP superglobal is used to retrieve information about files uploaded via an HTTP POST request?

Accepted Answer

The $_FILES superglobal is an associative array containing items uploaded to the current script via the HTTP POST method. While $_POST captures form field data, it does not contain file metadata or temporary path information. $_GET is used for URL parameters, and $_UPLOAD is not a valid PHP superglobal.
