PHPを使用してカスタム配列をマッピングする方法は？

Question

私は以下のような配列を持っています。 atrributesは、配列ごとにorder_id、qty、sell_price、product_nameおよびmerchant_nameです。私は、同じORDER_IDに基づいてマップと同じORDER_ID 1より大きい

[items:protected] => Array 
    (
     [0] => stdClass Object 
      (
       [order_id] => 1 
       [qty] => 1 
       [sell_price] => 45000.00 
       [product_name] => Omni Bars Cokelat Kelapa 
       [merchant_name] => Health & Co. 
      ) 

     [1] => stdClass Object 
      (
       [order_id] => 1 
       [qty] => 1 
       [sell_price] => 55000.00 
       [product_name] => Trim Eats Strawberry Banana Cream Overnight Oats 
       [merchant_name] => Trim Eats 
      ) 

     [2] => stdClass Object 
      (
       [order_id] => 1 
       [qty] => 1 
       [sell_price] => 28000.00 
       [product_name] => Everything Banana Keripik Pisang Rumput Laut 
       [merchant_name] => EverythingBanana 
      ) 

     [3] => stdClass Object 
      (
       [order_id] => 2 
       [qty] => 1 
       [sell_price] => 35000.00 
       [product_name] => Naked Bar Banana Nutter 
       [merchant_name] => Naked Foodss 
      ) 

     [4] => stdClass Object 
      (
       [order_id] => 3 
       [qty] => 1 
       [sell_price] => 200000.00 
       [product_name] => Health & Co. Paket Detoks 1 Hari 
       [merchant_name] => Health & Co. 
      ) 

     [5] => stdClass Object 
      (
       [order_id] => 3 
       [qty] => 1 
       [sell_price] => 38000.00 
       [product_name] => Health & Co. Paket 3 Botol Holy Kale 
       [merchant_name] => Health & Co. 
      ) 

    ) 

私はORDER_IDがある鍵を使用してこのような何かに配列をマッピングしたい場合は、アレイになる属性を変更したいです。

[1] => stdClass Object 
     (
      [qty] => [1,1,1] 
      [sell_price] => [45000.00, 55000.00, 28000.00] 
      [product_name] => [Omni Bars Cokelat Kelapa, Trim Eats Strawberry Banana Cream Overnight Oats, Everything Banana Keripik Pisang Rumput Laut] 
      [merchant_name] => [Health & Co, Trim Eats, EverythingBanana] 
     ) 
    [2] => so on.... 

私はそれを固執しました。私を助けてください。

ルックこのソリューション：

//$data - your array 

$result = []; 
foreach ($data as $item) { 
    $result[$item['order_id']]['qty'][] = $item['qty']; 
    $result[$item['order_id']]['sell_price'][] = $item['sell_price']; 
    $result[$item['order_id']]['product_name'][] = $item['product_name']; 
    $result[$item['order_id']]['merchant_name'][] = $item['merchant_name']; 
} 

// $result your result array
