搜索數組？然後獲取子值？

Question

我有一個數組，看起來像

[products] => Array 
     (
      [0] => stdClass Object 
       (
        [order_product_id] => 91385 
        [order_id] => 5065 
        [nid] => 2140 
        [title] => Gi Treasure 
        [manufacturer] => 
        [model] => giftcard 
        [qty] => 5 
        [cost] => 0.00000 
        [price] => 25.00000 
        [weight] => 0 
        [data] => Array 
         (
          [gift_description] => HJello! 
          [gift_email] => dubccom 
          [gift_sender] => Hello 
          [gift_sendDate] => 2011-10-25 
          [gift_title] => Thesure 
          [gift_card] => 2130 
          [gift_price] => 25 
          [gift_qty] => 5 
          [gift_name] => Steveek 
          [module] => uc_product 
          [cert_code] => 8-x8mfqXyUYXze 
         ) 

        [order_uid] => 1 
       ) 

      [1] => stdClass Object 
       (
        [order_product_id] => 91386 
        [order_id] => 5065 
        [nid] => 2140 
        [title] => Gift asure 2 
        [manufacturer] => 
        [model] => giftcard 
        [qty] => 1 
        [cost] => 0.00000 
        [price] => 35.00000 
        [weight] => 0 
        [data] => Array 
         (
          [gift_description] => Hello There! 
          [gift_email] => dubcaom 
          [gift_sender] => Hello 
          [gift_sendDate] => 2011-10-25 
          [gift_title] => The Holida 
          [gift_card] => 2134 
          [gift_price] => 35 
          [gift_qty] => 1 
          [gift_name] => Steven 
          [module] => uc_product 
          [cert_code] => 9-8xsxgDW9yrMq 
         ) 

        [order_uid] => 1 
       ) 

     ) 

我想從產品陣列中的數據陣列，其中order_product_id（所以如果它是91385，我會得到

[data] => Array 
         (
          [gift_description] => Hello 
          [gift_email] => dubccom 
          [gift_sender] => Hello 
          [gift_sendDate] => 2011-10-25 
          [gift_title] => Thesure 
          [gift_card] => 2130 
          [gift_price] => 25 
          [gift_qty] => 5 
          [gift_name] => Steveek 
          [module] => uc_product 
          [cert_code] => 8-x8mfqXyUYXze 
         ) 

任何幫助如何我可以這樣做？

Answer 1

$prod_data = false; 
foreach ($products as $product) 
{ 
    if ($product->order_product_id == 91385) 
    { 
     $prod_data = $product->data; 
     break; 
    } 
} 
if ($prod_data) { 
    // knock yourself out 
} 

神似簡單的英語，是吧？

Answer 2

function search_products($id,$products) 
{ 
    $id = intval($id); 
    foreach($products as $product) 
    { 
     if($product->order_product_id == $id) 
     { 
      return($product->data); 
     } 
    } 
    return null; 
} 

一個受過教育的猜測，你在找什麼。稱它爲search_products(91385, $products)。如果它返回null，它沒有找到產品ID。我還增加了一個對intval的調用，所以如果你依靠用戶輸入來實現這個功能，無論如何它都將是一個int。如果您已經將其清理爲int，這並不會造成傷害。

編輯：誤讀原始帖子。從數組語法更新爲對象屬性語法。

Answer 3

function data_by_order ($arr, $orderId) { 
    foreach ($arr as $item) { // Loop the array 
    if ($item->order_product_id == $orderId) { // Test this item for the right order id 
     return $item->data; // Return the data array 
    } 
    } 
    return FALSE; // Return false if we didn't find it 
} 

// Example usage: 
$data = data_by_order($array,91385); 
print_r($data);
