我使用search_array，和我假設，因爲它是多層面是不找到它。我怎樣才能遞歸搜索？我也嘗試了一些我在網上找到的例子，但是我找不到任何適合我需要的東西。

您知道什麼** **取消設置在PHP ???? –

顯示你到目前爲止嘗試過的。 –

我這樣做，但不是在多維數組中。 – moustiluigi

您只需要爲主要downloads索引運行unset。而對於子陣列，只需循環訪問$array['libraries']並保持未設置子陣列downloads字段。

unset($array['downloads']); /* Unset the downloads field within the main array */ 

foreach ($array['libraries'] as &$arr) { 
    unset($arr['downloads']); /* Unset the downloads field within the subarray */ 
}

這個怎麼

function array_unset_recursive(&$array, $removeKey) { 
    foreach ($array as $key => &$value) { 
     if($key == $removeKey){ 
      unset($array[$key]); 
     } 
     else if (is_array($value)) { 
      array_unset_recursive($value, $removeKey); 
     } 
    } 
} 

array_unset_recursive($arr, 'downloads');
