在PHP创建的iCalendar文件中共享Google日历的设置

I have a PHP script which makes an VCALENDAR file with events in it. All is well and Google Calendar reads it from an URL or if I insert it manually.

The problem is, only I can see it. I want the calendar to be viewable for everyone. How can I achieve this by editing the VCALENDAR file? So to set the agenda options (Anyone Can) to See all event details. Now it is set (when someone else adds it) to Anyone can: View nothing.

Thanks in advance!

Did you include a class component?

CLASS:PUBLIC

Wikipedia has more information about the iCalendar format.
