$_REQUEST
HTTP Request variables
Description
An associative array that by default contains the contents of $_GET, $_POSTListendand $_COOKIE.
Notes Is-superglobal
When running on the command line, this will not include the argv and argc entries; these are present in the $_SERVER array.
The variables in $_REQUEST are provided to the script via the GET, POST, and COOKIE input mechanisms and therefore could be modified by the remote user and cannot be trusted. The presence and order of variables listed in this array is defined according to the PHP request_order, and variables_order configuration directives.
