能够在print_r() 的输出中看到一个变量，但不确定如何在代码中访问它

如何从该数组内的 WP_User 对象中提取 ID:

数组([0] =>大批([盖子] =>WP_用户对象([数据] =>标准类对象([ID] =>24[用户登录] =>约翰福[user_pass] =>$P$BP0Qa4[user_nicename] =>约翰-富[用户电子邮件] =>[e-mail][user_url] =>[用户注册] =>2012-10-10 11:16:24[user_activation_key] =>[用户状态] =>0[显示名称] =>约翰福)[ID] =>24[大写] =>大批([委员会] =>1)[cap_key] =>sa_wp_capabilities[角色] =>大批([0] =>委员会)[全部大写] =>大批([edit_posts] =>1[阅读] =>1[级别_1] =>1[级别_0] =>1[删除帖子] =>1[委员会] =>1)[过滤器] =>)[lid_rol] =>沃尔兹特))

我使用以下代码:

';foreach($values 作为 $value){foreach ($value['lid'] 作为 $liddata) {echo $liddata->ID;}//很高兴看到您正在使用的内容echo '
';print_r($values);echo '</pre>';}回声'</ul>';}}}?>
它返回用户id，还有很多如下注意事项:

注意:试图获取非对象的属性
有人可以帮我吗?
解决方案
我觉得问题出在这里:foreach ($value['lid'] as $liddata) {
此时，$value['lid'] 是 WP_User 对象本身，因此 foreach 最终会遍历  的所有属性WP_User 对象.
如果你去掉那个 foreach，你应该能够从 $value['lid'] 直接访问对象的公共属性(例如 $value['lid']->ID 或 $value['lid']->roles[0]).
希望有所帮助.

How do I pull the ID from the WP_User object inside this array:
Array
(
[0] => Array
    (
        [lid] => WP_User Object
            (
                [data] => stdClass Object
                    (
                        [ID] => 24
                        [user_login] => John Foo
                        [user_pass] => $P$BP0Qa4
                        [user_nicename] => john-foo
                        [user_email] => [e-mail]
                        [user_url] =>

                        [display_name] => John Foo
                    )

                [ID] => 24
                [caps] => Array
                    (
                        [commissie] => 1
                    )

                [cap_key] => sa_wp_capabilities
                [roles] => Array
                    (
                        [0] => commissie
                    )

                [allcaps] => Array
                    (
                        [edit_posts] => 1
                        [read] => 1
                        [level_1] => 1
                        [level_0] => 1
                        [delete_posts] => 1
                        [commissie] => 1
                    )

                [filter] => 
            )

        [lid_rol] => Voorzitter
    )
)
And I use the following code:
<?php 

$rows = get_field('commissie_lid');
if($rows)
{
    foreach($rows as $row)
    {
        $values = get_field('commissie_lid');
            if($values)
            {
                echo '<ul>'; 
                foreach($values as $value)
                {
                    foreach ($value['lid'] as $liddata) {
                        echo $liddata->ID;                  

                }

               // allways good to see exactly what you are working with
               echo '<pre>';
                   print_r($values);
               echo '</pre>';

            } 
            echo '</ul>';
        } 
    }

}

 ?>
It returns the user id, but also a lot of the following notices:

Can someone help me?
解决方案
I think the problem is here: foreach ($value['lid'] as $liddata) {

At that point, $value['lid'] is the WP_User object itself, so that foreach ends up iterating over all of the properties of the WP_User object.

If you eliminate that foreach, you should be able to directly access the public properties of the object from $value['lid'] (e.g. $value['lid']->ID, or $value['lid']->roles[0]).

Hope that helps.
