在數組中回顯嵌套的 stdClass object

Question

以下數據存儲為 PHP 多維數組。 我如何從這個數組中呼出“閱讀/社交”？ 這是我第一次玩多維 arrays 和 object 面向編程的經驗，所以我不確定從哪里開始。

我試過echo $roster[0]->class; 但這不起作用。 我究竟做錯了什么？

Array
(
    [0] => stdClass Object
        (
            [class] => stdClass Object
                (
                    [alternateLink] => https://classroom.google.com/c/MjE5ODTA3NTc0
                    [calendarId] => c_classroom96eb75a@group.calendar.google.com
                    [courseGroupEmail] => test@school.org
                    [courseState] => ACTIVE
                    [creationTime] => 2021-01-02T17:28:07.444Z
                    [description] => 
                    [descriptionHeading] => 
                    [enrollmentCode] => sretszz
                    [guardiansEnabled] => 
                    [id] => 219850017574
                    [name] => 🔴 Reading/Social
