如何從多維數組中獲取父數組索引php

當我打印它時，它顯示如下結果。

，我有一個變量$ categ.For例如$ CATEG =「homeandgardenairconditioner型」那麼我想知道他的「名」父數組的索引是「homeandgardenairconditioner-鍵入「

即--- O/p應爲9

如何得到這個指標。請幫我

感謝

@PLB我不知道如何遍歷這個數組，所以我首先檢查它的名字，然後得到它的父數組索引th at爲什麼我問。謝謝 –

它是否已經定義您的值將位於數組的第一維？或者它應該用於在'$ array [$ i] [$ j] [$ k] [$ etc]''中查找值？ –

@ Frederik.L我有'名稱'。你可以寫你的代碼嗎？謝謝 –

可能重複，我認爲你正在尋找這樣的：

function getIndex($name, $array){ 
    foreach($array as $key => $value){ 
     if(is_array($value) && $value['name'] == $name) 
       return $key; 
    } 
    return null; 
}

是的考拉。我得到了這個謝謝 –

試試這個，

function find_parent($array, $needle, $parent = null) { 
    foreach ($array as $key => $value) { 
     if (is_array($value)) { 
      $pass = $parent; 
      if (is_string($key)) { 
       $pass = $key; 
      } 
      $found = find_parent($value, $needle, $pass); 
      if ($found !== false) { 
       return $found; 
      } 
     } else if ($key === 'id' && $value === $needle) { 
      return $parent; 
     } 
    } 

    return false; 
} 

$parentkey = find_parent($array, '0002');

的PHP - Find parent key of array

它沒有給我解決方案。我的情況是littile不同。我不搜索另一個陣列，而我只是想匹配「名稱」 –
