iCal sync with database

Question

Let's say I have a PHP file that generates an iCal calendar (file.ics) and I import this file in my smartphone.

My question is: how do I sync the changes made on the smartphone with the server that hosts the iCal file?

Thank you

Syncing is not that easy and plain process as just importing the data, and cannot be described here in 'easy steps'. There is an API on iPhone to access calendars data, via it you should check the data, understand which records were changed locally and on remote server, and decide what to copy, what to delete, where are conflicts, etc.
