<?php
// Example from PHPlibraries.com
require_once 'libs/symfony/security-core/7.3.0/loader.php';
require_once 'libs/symfony/http-foundation/7.3.0/loader.php';
require_once 'libs/symfony/event-dispatcher/7.3.0/loader.php';
require_once 'libs/symfony/dependency-injection/7.3.0/loader.php';

use Symfony\Component\Security\Core\Authorization\AuthorizationChecker;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;
use Symfony\Component\HttpFoundation\Request;

$obj = new AuthorizationChecker();
echo '✅ Test OK: ' . get_class($obj);
?>
