You can use unique('field_name'); instead of groupBy('field_name'); /** * Show the application dashboard. * * @return \Illuminate\Http\Response */ public function index() { $messages = Message::select("*") ->where('receiver_id',$id) ->orderBy('created_at', 'desc') ->get() ->unique('sender_id'); dd($messages); }
