Php 如何将包含多个事件的ICS文件导入多个日历？

生成ICS文件后，当我转到导入Outlook/Google时，我发现只有一个事件在

addbyURL

时被导入。即使使用

Import

选项，它也会在导入的9个事件中给出一条消息

1

在检查了多个链接、iCalendar规范之后，我很清楚，这方面的文档非常稀少。另外，到目前为止，没有人能够回答这类问题。有“类似”的问题，尽管没有一个对我和其他许多人有效

代码
PHP
生成的ICS（iCalendar）文件如下所示：

挑战
未正确分析全天事件
导入到其他日历无法正常工作
文档太宽泛，示例太少
图书馆对此的支持非常有限
当单击打开windows 10日历中的同一ics文件并显示所有事件时，该文件工作正常（所有事件都已加载）。然而，正如前面多篇文章所提到的，时间仍然是关闭的，所有的一天事件都在第二天的12点结束，而不管24小时的持续时间是多少
像Stanza.co这样的流行网站创建自己的日历，然后允许用户从所有其他日历订阅。这不是开源的
我所研究的和你使用任何搜索栏都能找到的一样。围绕整个主题，我在多个网站上浏览了至少100篇或更多的文章。这是我第二次尝试得到答案。
有错误。将您的ics文件通过各种ics验证器。我尽可能多地做，因为他们不会说同样的话。谷歌不会告诉你什么是错误的，但会拒绝无效的事件。使用一个验证器（此）和您的ics内容，我得到：

问题！发现5个错误

谢谢，这很合理，可以。我已经停止了这方面的开发，开始研究outlook和google日历API本身。Outlook MSGraph API似乎易于使用。我还不知道这是否适合我的项目。谢谢，这是合理的，可以。我已经停止了这方面的开发，开始研究outlook和google日历API本身。Outlook MSGraph API似乎易于使用。我还不知道这是否适合我的项目。
