php-symfonyHow to use Ajax with PHP Symfony?

Ajax (Asynchronous JavaScript and XML) can be used with PHP Symfony to create dynamic web applications.

To use Ajax with Symfony, you need to create a route that will handle the Ajax request and return a response.

Example code

// src/Controller/AjaxController.php

namespace App\Controller;

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;

class AjaxController
{
    public function ajaxAction(Request $request)
    {
        // Get the data from the request
        $data = $request->request->get('data');

        // Do something with the data
        // ...

        // Return a response
        return new Response('OK');
    }
}

Output example
