Error : Object of class Illuminate\Support\Collection could not be converted to int

Please help me, what should I do?

Answer 1

get() return object of table not single value.

use like this way DB::table('listrik_depan')->value('depan_pakaiwbp1200') instead of get()

$total1 = DB::table('listrik_depan')->value('depan_pakaiwbp1200');
$total2 = DB::table('listrik_belakang')->value('belakang_pakaiwbp60');

$seluruh = $total1 + $total2;
dd($seluruh);
