Do you have experience working with the Symfony framework?

Yes, I have experience working with Symfony. Symfony is a popular PHP framework that uses components to build web applications. It supports the MVC architecture, provides powerful tools for routing, database interaction through Doctrine, the Twig templating system, and many other features.

Example of a simple controller in Symfony:

// src/Controller/DefaultController.php
namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;

class DefaultController extends AbstractController
{
    /**
     * @Route("/", name="homepage")
     */
    public function index(): Response
    {
        return new Response('Hello, Symfony!');
    }
}

This code defines a route and returns a simple response when accessing the root of the site.
