$_FILES
Selecting $_GET or $_POST depending on the request method isn't a general solution, since it's possible for an HTTP request to have both posted content and a query string in the URI.
If you want to allow for this possibility, you can use
<?php
$req = array_merge($_GET, $_POST);
?>
or vice versa, depending on which you want to be used in the event of a clash between them.

Note
Notă: Aceasta este o variabilă 'superglobală', sau globală automată. Aceasta pur şi simplu înseamnă că ea este disponibilă în toate circumstanţele pe parcursul script-ului. Nu este nevoie de a scrie global $variable; pentru a o accesa din funcţii sau metode.
Notă: When running on the command line , this will not include the argv and argc entries; these are present in the $_SERVER array.
Notă: 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 variables_order configuration directive.

Don't forget, because $_REQUEST is a different variable than $_GET and $_POST, it is treated as such in PHP -- modifying $_GET or $_POST elements at runtime will not affect the ellements in $_REQUEST, nor vice versa.
e.g:
<?php
$_GET['foo'] = 'a';
$_POST['bar'] = 'b';
var_dump($_GET); // Element 'foo' is string(1) "a"
var_dump($_POST); // Element 'bar' is string(1) "b"
var_dump($_REQUEST); // Does not contain elements 'foo' or 'bar'
?>
If you want to evaluate $_GET and $_POST variables by a single token without including $_COOKIE in the mix, use $_SERVER['REQUEST_METHOD'] to identify the method used and set up a switch block accordingly, e.g:
<?php
switch($_SERVER['REQUEST_METHOD'])
{
case 'GET': $the_request = &$_GET; break;
case 'POST': $the_request = &$_POST; break;
.
. // Etc.
.
default:
}
?>
