Questions:

I want to add new element in $items array, I don’t want to use joins for certain reasons.

$items = DB::select(DB::raw('SELECT * FROM items WHERE items.id = '.$id.'  ;'));
        foreach($items as $item){
            $product = DB::select(DB::raw(' select * from product
                   where product_id = '. $id.';' ));

            $item->push($product);
        }

what should i do, please help, thnx in advance

How to&Answers:

It looks like you have everything correct according to Laravel docs, but you have a typo

$item->push($product);

Should be

$items->push($product);

I also want to think the actual method you’re looking for is put

$items->put('products', $product);

Answer:

As mentioned above if you wish to as a new element your queried collection you can use:

    $items = DB::select(DB::raw('SELECT * FROM items WHERE items.id = '.$id.'  ;'));
    foreach($items as $item){
        $product = DB::select(DB::raw(' select * from product
               where product_id = '. $id.';' ));

        $items->push($product);
        // or 
        // $items->put('products', $product);
    }

but if you wish to add new element to each queried element you need to do like:

    $items = DB::select(DB::raw('SELECT * FROM items WHERE items.id = '.$id.'  ;'));
    foreach($items as $item){
           $product = DB::select(DB::raw(' select * from product
                 where product_id = '. $id.';' ));

          $item->add_whatever_element_you_want = $product;
    }

add_whatever_element_you_want can be whatever you wish that your element is named (like product for example).
