通過隨機/動態數組中的鍵搜索值

Question

什麼是搜索多維數組的關鍵。 像

Array 
(
    [items] => Array 
     (
      [0] => Array 
       (
        [0] => Array 
         (
          [item1] => Array 
           (
            [item] => a 
            [url] => xys.com 
           ) 

         ) 

       ) 

      [1] => Array 
       (
        [1] => Array 
         (
          [item2] => Array 
           (
            [url] => xys.com 
            [count] => 5 
           ) 

         ) 

       ) 

      [2] => Array 
       (
        [2] => Array 
         (
          [item3] => Array 
           (
            [url] => abc.com 
            [count] => 5 
           ) 

         ) 

       ) 

      [3] => Array 
       (
        [3] => Array 
         (
          [item4] => Array 
           (
            [meta] => b 
            [count] => 5 
           ) 

         ) 

       ) 

      [4] => Array 
       (
        [4] => Array 
         (
          [item5] => Array 
           (
            [url] => abc.com 
            [count] => 5 
           ) 

         ) 

       ) 

     ) 

) 

我想第一個出現或鑰匙「URL」和值的值應該是「xys.com」

該陣列可以是隨機/動態的，所以我不能重複它使用它的關鍵，我只是希望它的關鍵

感謝

我找到了解決辦法第一次發生搜索和這個功能非常適用於上面的例子：

function searchArrayValueByKey(array $array, $search) { 
foreach (new RecursiveIteratorIterator(new RecursiveArrayIterator($array)) as $key => $value) { 
    if ($search === $key) 
    return $value; 
} 
return false; 
}
