• Accessing StdClass value with colon :protected 4 answers

I'm trying to access the properties of my SheriffUser instance to store them in separate variables and manipulate them ($email, $password, $fullname...) I tried to do a get_object_vars but it returns nothing.

An instantiation doesn't work either because there are missing properties.

namespace Aecf\DemoBundle\AuthTest;

use Symfony\Component\Security\Core\Event\AuthenticationEvent;
use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorageInterface;
use Aecf\SecurityBundle\Security\Core\User;

class AuthTestPrint
{
    public function printSomething(AuthenticationEvent $event){
        dump('Authentication detected');
        $token = $event->getAuthenticationToken();
        $user=$token->getUser();
        dump($user);
        var_dump($user);
        //$user = new User\SheriffUser($token->getUser());
    }
}

Here is the result of dump(user);

AuthTestPrint.php on line 17:
SheriffUser {#443 ▼
  -email: "user"
  -actions: array:1 [▶]
  -password: "user"
  -fullName: "user"

  -shops: ArrayCollection {#444 ▶}
  -locale: null
  -refreshToken: null
  -expiresAt: null
}

The result of var_dump($user);

Answer 1

try this for example:

$email = $user->getEmail();

Usually in your entity you have getter and setter because property are private, in this case I have use a getter getEmail.
