How do I get the logged in user's id in symfony 4?

The user can log in, but i need his id to show his profile. Since i'm working in symfony 4, the many possible answers i've found were obsolete.

https://symfony.com/doc/current/security.html#retrieving-the-user-object

After authentication, the User object of the current user can be accessed via the getUser() shortcut (which uses the security.token_storage service). From inside a controller, this will look like:

public function index()
{
    $this->denyAccessUnlessGranted('IS_AUTHENTICATED_FULLY');

    $user = $this->getUser();
}

The user will be an object and the class of that object will depend on your user provider. But, you didn't tell us what user provider you are using, so I have no way of telling you, beyond this, how to get to the id itself.

One other way to get the user:

An alternative way to get the current user in a controller is to type-hint the controller argument with UserInterface (and default it to null if being logged-in is optional):

use Symfony\Component\Security\Core\User\UserInterface\UserInterface;

public function indexAction(UserInterface $user = null)
{
    // $user is null when not logged-in or anon.
}

This is only recommended for experienced developers who don't extend from the Symfony base controller and don't use the ControllerTrait either. Otherwise, it's recommended to keep using the getUser() shortcut.
