Code Integration Example

Make sure to include the correct namespace and class paths for proper usage.

<?php
// Example from PHPlibraries.com
require_once 'libs/symfony/http-kernel/7.3.4/loader.php';
require_once 'libs/symfony/debug/4.4.44/loader.php';
require_once 'libs/symfony/http-foundation/7.3.4/loader.php';

use Symfony\Component\HttpKernel\HttpKernel;
use Symfony\Component\HttpKernel\Kernel;

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