<?php
$request = new Gongo\MercifulPolluter\Request;
$request->pollute();

// main routine...

If use the session, call Gongo\MercifulPolluter\Session::pollute() after session_start():

session_start();

/**
 * $_SESSION['user_id'] = 'gongo'
 */

(new Gongo\MercifulPolluter\Session)->pollute();

var_dump($user_id); // string(5) "gongo"

// Reference global variables to session.
$user_id = 'taro';
var_dump($_SESSION['user_id']); // string(4) "taro"

If want to apply magic_quotes_gpc, call Gongo\MercifulPolluter\Request::enableMagicQuotesGpc():

<?php
/**
 * example.com/?foo=1'2'3
 */

$request = new Gongo\MercifulPolluter\Request;
$request->enableMagicQuotesGpc();
$request->pollute();

// $_GET['foo'] => "1\'2\'3"
//        $foo  => "1\'2\'3"
