如何匹配两个数组的值？

Question

使用PHP，我如何才能将订阅者与这两个数组的用户进行匹配？

$用户

Array 
(
    [0] => stdClass Object 
     (
      [meta_id] => 1 
      [email] => name@example.com 
     ) 

) 

$用户

Array 
(
    [0] => stdClass Object 
     (
      [ID] => 1 
      [user_email] => name@example.com 
     ) 

    [1] => stdClass Object 
     (
      [ID] => 2 
      [user_email] => name2@example.com 
     ) 

我认为这将做到这一点...

<?php 
foreach ($users as $user) { 
    if (in_array('name@example.com', $subscribers)) { 
     echo 'Matched user'; 
    } 
}

foreach ($users as $user) { 
    foreach ($subscribers as $subscriber) { 
     if ($user->user_email === $subscriber->email) { 
      echo 'Matched user'; 
      break; 
     } 
    } 
}
