php - 从数组获取ID的值

我有$user = wp_get_current_user();数组。当我打印时，它将显示为

WP_User Object
(
    [data] => stdClass Object
        (
            [ID] => 169 // I wanted the Value of ID
            [user_login] => [email protected]
            [user_pass] => $P$BN2ibVoWTXB1DIsdcTnpVV03DBz8od0
            [user_nicename] => madhurigmail-com
            [user_email] => [email protected]
            [user_url] =>
            [user_registered] => 2015-11-17 09:54:57
            [user_activation_key] =>
            [user_status] => 0
            [display_name] => Madhuri Kashid
            [latitude] =>
            [longitude] =>
            [role] =>
        )

我只想要ID的值。
我想将ID的存储值放入$UserId
提前致谢

最佳答案

您正在获取对象而不是数组

尝试

$UserId = $user->data->ID;
