Answer 1

You have to reshape your data so it contains price against the respective id . You can do this before the loop:

$result = collect($referralData->product)->groupBy('id')->map(function ($item) {
            return $item->sum('price');
        });

After that, in your loop, do the following:

@foreach($result as $id => $price)
<tr>
<td>{{$id}}</td>
<td>{{$price}}</td>
</tr>
@endforeach
