使用PHP以外的變量Foreach循環

Question

我想在foreach循環之外輸出用戶名和用戶電子郵件。我正試圖發送電子郵件給某個用戶角色中的所有WordPress用戶。

這裏是我的代碼：

// Get users and their roles 
    $user_args = array(
     'role__in' => 'new_role', 
     'orderby' => 'user_nicename', 
     'order' => 'ASC' 
    ); 
    $users = get_users($user_args); 

    foreach ($users as $user) :  
     $user_name = $user->user_email; 
     $user_email = $user->display_name;   
    endforeach; 

這樣我就可以在隨後的頁面，即其他領域使用它們:.

echo 'Hello, ' . $user_name; 
echo 'Send to: ' .$user_email; 

我打印出來的$用戶數組，它包含以下內容：

Array 
(
    [0] => WP_User Object 
     (
      [data] => stdClass Object 
       (
        [ID] => 46

Answer 1

如果你想發送電子郵件給所有用戶提供了一定的作用，嘗試這樣的事情：

// Get users and their roles 
$user_args = array(
    'role__in' => 'new_role', 
    'orderby' => 'user_nicename', 
    'order' => 'ASC' 
); 

$users = get_users($user_args); 

foreach ($users as $user) :  
    $user_email = $user->user_email; 
    $user_name = $user->display_name; 
    send_email($user_name, $user_email);   
endforeach; 

，然後寫電子郵件功能：

function send_email($name, $email) { 
    // Do email sending stuff here with $name & $email 
}
