如果數組的值是相同的然後添加到現有的數組

Question

我一直與這一整天都在戰鬥，並希望另一組眼睛也許給我一些見解。我不確定我是否正確地接近這個方向。我有一個列出了購買產品的數組，但是如果產品在數組中重複，我想將這些屬性合併在一起。

$order = $order->getProducts(); 
$newArray = array(); 
foreach ($order as $order) 
{ 
    $product = new Product($order['product_id']); 

    $combination = new Combination($order['product_attribute_id']); 
    $attribute = $combination->getAttributesName($context->language->id); 
    foreach ($attribute as $attribute) 
     $attributeName = $attribute['name']; 

    $newArray[] = array(
     'id_product' => $order['product_id'], 
     'name' => $product->name[$context->language->id], 
     'combination' => array(
      'id_product_attribute' => $order['product_attribute_id'], 
      'type' => $attributeName 
     ) 
    ); 
} 

我的陣列找出來這樣

Array (
[0] => Array 
    (
     [id_product] => 117 
     [name] => Sidewinder 1-Foot Extension 
     [combination] => Array 
      (
       [id_product_attribute] => 172 
       [type] => Black 
      ) 

    ) 

[1] => Array 
    (
     [id_product] => 117 
     [name] => Sidewinder 1-Foot Extension 
     [combination] => Array 
      (
       [id_product_attribute] => 173 
       [type] => Black & Yellow 
      ) 

    ) 

[2] => Array 
    (
     [id_product] => 119 
     [name] => ENV100 
     [combination] => Array 
      (
       [id_product_attribute] => 0 
       [type] => Black & Yellow 
      ) 

    ) 

) 

我想嘗試實現這一

Array (
[0] => Array 
    (
     [id_product] => 117 
     [name] => Sidewinder 1-Foot Extension 
     [combination] => Array 
      (
       [0] => Array 
        (
         [id_product_attribute] => 172 
         [type] => Black 
        ) 
       [1] => Array 
        (
         [id_product_attribute] => 173 
         [type] => Black & Yellow 
        ) 
      ) 

    ) 
[1] => Array 
    (
     [id_product] => 119 
     [name] => ENV100 
     [combination] => Array 
      (
       [id_product_attribute] => 0 
       [type] => 
      ) 

    ) 

)

也許能夠使它看起來更好一點，但這應該工作：

foreach ($order as $order) { 
    $product = new Product($order['product_id']); 
    $combination = new Combination($order['product_attribute_id']); 
    $attribute = $combination->getAttributesName($context->language->id); 

    $newArray[$order['product_id']] = array(
      'id_product' => $order['product_id'], 
      'name' => $product->name[$context->language->id], 
    ); 

    foreach ($attribute as $attr) {   
     $newArray[$order['product_id']]['combination'][] => array(
       'id_product_attribute' => $attr['id'], // a guess 
       'type' => $attr['name'], 
     ); 
    } 
} 

個數組鍵將是product_id所以如果你想讓他們爲你展示，然後在循環之後：

$newArray = array_values($newArray); 

我帶着刺不知道這是什麼意思做：

foreach ($attribute as $attribute) 
     $attributeName = $attribute['name'];
