$_FILES
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:
}
?>

Notas
Nota:
Esta é uma 'superglobal', ou global automática, variável. Isto simplismente significa que ela está disponível em todos escopos pelo script. Não há necessidade de fazer global $variable; para acessá-la dentro de uma função ou método.
Nota:
Quando executando em linha de comando , esta não incluirá as entradas argv e argc; estas estão presentes no array $_SERVER.
Nota:
As variáveis em $_REQUEST são providas para o script via mecanismos de entradas GET, POST, e COOKIE e portando poderia ser modificadas por um usuário remoto e não podem ser confiadas. A presença e ordem das variáveis listadas neste array é definido de acordo com a diretiva de configuração do PHP variables_order.

The default php.ini on your system as of in PHP 5.3.0 may exclude cookies from $_REQUEST. The request_order ini directive specifies what goes in the $_REQUEST array; if that does not exist, then the variables_order directive does. Your distribution's php.ini may exclude cookies by default, so beware.

I wrote a function because I found it inconvenient if I needed to change a particular parameter (get) while preserving the others. For example, I want to make a hyperlink on a web page with the URL http://www.example.com/script.php?id=1&blah=blah+blah&page=1 and change the value of "page" to 2 without getting rid of the other parameters.
<?php
function add_or_change_parameter($parameter, $value)
{
$params = array();
$output = "?";
$firstRun = true;
foreach($_GET as $key=>$val)
{
if($key != $parameter)
{
if(!$firstRun)
{
$output .= "&";
}
else
{
$firstRun = false;
}
$output .= $key."=".urlencode($val);
}
}
if(!$firstRun)
$output .= "&";
$output .= $parameter."=".urlencode($value);
return htmlentities($output);
}
?>
Now, I can add a hyperlink to the page (http://www.example.com/script.php?id=1&blah=blah+blah&page=1) like this:
<a href="<?php echo add_or_change_parameter("page", "2"); ?>">Click to go to page 2</a>
The above code will output
<a href="?id=1&blah=blah+blah&page=2">Click to go to page 2</a>
Also, if I was setting "page" to a string rather than just "2", the value would be urlencode()'d.
<a href="<?php echo add_or_change_parameter("page", "banana+split!"); ?>">Click to go to page banana split!</a>
would become
<a href="?id=1&blah=blah+blah&page=banana+split%21">Click to go to page banana split!</a>

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 that the default distribution php.ini files does not contain the 'C' for cookies, due to security concerns.
