php - How to sum at once in loop without waiting? -

my view blade :

... @foreach($orders $order)     ...     <td>{{ $order->sumtotal['total'] }}</td>     ... @endforeach ... 

my model :

public function getsumtotalattribute() {     $total = order::where('year','=', '2017')                   ->sum('total');     return ['total'=>$total]; }
