Integrating a WordPress user login with Symfony is pretty painless if you need to share user sessions.  Just don’t rely solely on that WordPress cookie, but cross reference a randomly assigned hash that can reference back to the WordPress user’s table.  When you get your system to authenticate a user and you find your FOS User Bundle session expired and forces the user to log back in, you can save them the trouble by “synchronizing” the WordPress user session by logging them in automatically in the FOS User Bundle like so:


   $token = new UsernamePasswordToken($user, null, 'main', $user->getRoles());

Be sure to add this “use statement” up top in your controller/repo:

use Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken;
