In Symfony, PHP sessions are managed by PHP's $_SESSION superglobal variable. To change the phpsessid after login, you can regenerate the session id using session_regenerate_id() function. Here's how you can do it after login:


First, make sure you have started the session in your controller action method:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13

17

// src/Controller/SecurityController.php

namespace AppController;

use SymfonyBundleFrameworkBundleControllerAbstractController;
use SymfonyComponentHttpFoundationRequest;
use SymfonyComponentHttpFoundationResponse;

class SecurityController extends AbstractController
{
    public function login(Request $request): Response
    {
        // Check login credentials and log the user in
        
        // Regenerate the session id
        $request->getSession()->migrate(true);
        
        // Redirect to homepage or dashboard
        return $this->redirectToRoute('homepage');
    }
}


In the code snippet above, we are using the migrate(true) method to regenerate the session id. Setting the parameter to true will also delete the old session data.


After generating a new session id, you can redirect the user to the homepage or any other desired page. This will ensure that the session id is changed after a successful login.
