來自 2 個數組的多維數組

Question

我有 2 個數組，product_types 和 products，我正在嘗試制作一個多維數組，將產品放入主數組中的它們自己的 product_type 數組中。 產品有一個 product_type 值，我可以與之匹配。 我正在使用 php 和 mysql 來獲取信息。 我的問題是，如果我將多個產品分配給一個 product_type，那么它只顯示其中之一。 感謝您提供任何幫助！

foreach ($type_array as $key => $type):
       foreach ($product_array as $k =>$product):
           if($product['product_type'] == $type){
             $variables[$type][] = $product;
           }
       endforeach;
endforeach; 

我的陣列：

Answer 1
