Can and should lock work with the php sdk

Hi,

I’ve set up a website that uses lock.js to authenticate with auth0 on a login page.

If the user logins in successfully, it sends them to a index.php page.

The page calls the auth0 sdk and checks if a $userInfo exists.

  use Auth0\SDK\Auth0;

  $auth0 = new Auth0($auth0Config);

  try {
    $userInfo = $auth0->getUser();

    if(isset($userInfo['error'])) {
      throw new Exception();
    }

  } catch (Exception $e) {
    session_destroy();

    header("Location: " . APP_PATH);
    exit();
  }

Is this acceptable method of authenticating, should I even be combining lock with the php-sdk?

Thanks
