Php 使用FacebookGraphAPI获取所有成员列表（来自我自己的一个组）'；I don’’我不能得到完整的列表——我的代码中哪一部分出错了？

我开始使用FacebookGraphAPI，并注意到当我试图从我的组（我拥有的）中获取所有成员列表时，回显了用户名，我只得到（大约）4900个用户作为输出-我的组中有15K+用户！！！ 为了测试我对每个列表进行了var_dump-ed，它给了我127个数组，其中包含“more elements…”文本，因此我得出结论，回显列表是好的，但获取列表是错误的

我尝试使用Graph API资源管理器获取成员列表，它给出了相同的结果，错误的“下一步”链接带有奇怪的偏移量和限制参数，这些参数没有任何意义，我也没有输入

这是我现在的代码（滚动到“这里很酷”）：

这是一个已知的Facebook bug（2年多了），处于低优先级修复中

为了避免这种情况，我认为报废是唯一的最佳选择，不过，为了记录在案，这是自上次评论以来几乎一年后的错误报告，该错误仍然存在。我刚刚开始用这个SDK开发，知道这样的东西存在有点令人沮丧。请注意每个人-为了“帮助”facebook决定修复它，你们都应该订阅这个bug并评论说需要修复它。这是一个bug：developers.facebook.com/bug/267362886791339请大家注意——这是facebook的一个已知bug。为了“帮助”facebook决定修复它，你们所有人都应该订阅这个bug并评论你们需要修复它。这里是错误：developers.facebook.com/bugs/267362886791339
