PHP - How can i add a date/contact programatically to a CalDAV/CardDav Server?

Helo,

my aim is to install Radicale (https://radicale.org/) and create a CalDav calendar and CardDAV vCard.

My problem is that I don't know how to handle this in PHP. My aim is to:

1. get all dates from CalDAV calendar
2. insert a new date to CalDAV calendar, if it doesn't exists
3. insert a new contact to CardDav vCard, if it doesn't exists

Is there a CalDAV/CardDAV library in PHP, which can achieve this?

Thank you!
