Question

我有一个数组，我想在其中搜索并找出答案数组中的特定 id ，以及是否将其所有值传递给另一个数组并从主数组中删除它。我尝试了一堆循环，但它们只是让我的程序运行得更慢。我也尝试过：

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

但后来没有任何回复。我也尝试过cakephp 3中的收藏课，但这对我没有帮助。所以我把我的阵列放在这里希望有人会帮助我抛出这个。我应该提到我使用 cake php 3

Answer 1

你可以使用 Cakephp 的集合，你必须使用集合的匹配方法

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

Collection::match

在数组中查找特定值
