How to group by multiple columns in Laravel Query Builder?

Sometimes we may require to add group by with multiple columns, if we have mysql query then we can do it easily by using sql query. But if you want to give multiple columns in groupBy() of Laravel Query Builder then you can give by comma separated values as bellow example.

Example:

$data = DB::table("items_count")
	        ->select(
	            'items_count.*'
	            ,DB::raw("SUM(items_count.quantity) as total_quantity"))
	        ->groupBy('items_count.id_item','items_count.id_cat')
	        ->get();
print_r($data);
