在一個數組尋找一個特定值

-1

我有我願做一個搜索中，並瞭解是否有具體的ID在回答數組，如果它是其所有值傳遞到另一個陣列和陣列從主數組中移除它。我嘗試了一堆循環，但它們只是讓我的程序運行得更慢。我也嘗試：在一個數組尋找一個特定值

$key = array_search('2', array_column($myarray, 'id'));

但隨後被退回無關。我也在cakephp 3試過集合班，但那對我沒有幫助。所以我把我的陣列在這裏希望有人會幫我把這個扔掉。我應該使用蛋糕PHP 3

提到IM您可以使用集合CakePHP的，你必須使用收集的匹配方法

use Cake\Collection\Collection; 
$collection = new Collection($data['answers']); 
$answer = $collection->match(['answers.id' => 2]);

Collection::match

當我使用$ data ['answers']它說：只有一個數組或\ T可以使用可逆的Collection，但是當我只使用$ data時沒有錯誤，我爲$ collection做了每一件事，而我得到的是一個沒有我的第二個數組的ID = 2的數組，現在我該如何使用這個新集合$回答）因爲當我使用它們是空的和toArray（）顯示一個空數組 –
