php-ews 如何按日历主题搜索日历事件

Question

我正在使用https://github.com/jamesiarmes/php-ews 将 php 连接到交换服务器，到目前为止使用下面的代码没有问题。我可以连接到特定用户的邮箱，并可以检索他所有的日历事件。现在它拉所有的事件我想要的是只拉那些可以说“学生申请”的日历事件。在主题行中。是否可能。 ?

根据我的挖掘，您无法向 CalendarView 添加限制或排序顺序。我将找到的代码 here 添加到我的代码中以获取日历项目，我得到了以下 MessageText：

Restrictions and sort order may not be specified for a CalendarView.

这个MSDN page 中似乎列出了 FieldURI 变量的完整列表。

在您的情况下，我会在您的 foreach() 事件循环中放置一个正则表达式 strpos() 或类似表达式。然后，如果这种情况匹配执行您的功能。是的，你会有额外的事件，你不会做任何事情，但你至少可以过滤掉你想要的事件。
