试图在stdclass对象中获取非对象的属性

I'm trying to integrate with an API. Assuming the following code works.

$lists = $ac->api("list/list_", array("ids" => "all"));

            echo"<pre>"; print_r( $lists); echo"</pre>";

Outputs the following stdclass object

stdClass Object
(
    [0] => stdClass Object
        (
            [id] => 1
            [name] => List 3
            [cdate] => 2018-02-27 08:19:39
            [private] => 0
            [userid] => 1
            [subscriber_count] => 0
        )

    [result_code] => 1
    [result_message] => Success: Something is returned
    [result_output] => json
    [http_code] => 200
    [success] => 1
)

The following code

            foreach($lists as $list) {

                   echo $list->id;

               }

Shows me an error

Trying to get property of non-object

The line $list->id is wrong. How can I fix this?

    It's an odd structure, whats happening is its looping over result_code, result_message, result_output, success which the values are not objects.

    Either fix that, or do a check in the loop of sorts.

    foreach ($lists as $key => $list) {
        if (!is_numeric($key) || !is_object($list)) {
            continue;
        }
        echo $list->id;
    }
