Why constructor returns a null in Laravel 5.6

class AdminController extends Controller
{
    public function __construct() {
      $notification = Notification::where('read_status', 0)->get();
    }
}

In $notification variable constructor returns an null while data is present in notifications table.

Constructors do not return values, their only purpose is to instantiate class instances.

If you want to fetch data and use it in your class, you can do something like:

class AdminController extends Controller
{
    private $notifications;

    public function __construct()
    {
        $this->notifications = Notification::where('read_status', 0)->get();
    }
}

or

class AdminController extends Controller
{
    private $notifications;

    public function __construct()
    {
         $this->loadUnreadNotifications();
    }

    private function loadUnreadNotifications()
    {
        $this->notifications = Notification::where('read_status', 0)->get();
    }
}

After which you can use $this->notifications in your other controller methods.
