sortowanie tablicy obiektów drugą tablicą

$posP600Stock = [];//tablica obiektów w której każyd posiada metodę getWarehouseId
$warehouseIdsPriorities = [34,33,12,6];//priorytety sortowania !!! pamietaj o array flip !!! 

usort(
    $posP600Stock,
    function ($d1, $d2) use ($warehouseIdsPriorities) {
       return $warehouseIdsPriorities[$d1->getWarehouseId()] >= $warehouseIdsPriorities[$d2->getWarehouseId()] ? 1 : -1;
//lub return $warehouseIdsPriorities[$d1->getWarehouseId()] <=> $warehouseIdsPriorities[$d2->getWarehouseId()] ;
    }
);

//wynik pososrtowany po wartościach z drugiej tablicy
