An iCal Alternative
PHPiCalendar is a powerful, free, opensource alternative to iCal. Among its advantages is that you can run PHPiCalendar on most web servers and don't need a .mac account as you do with iCal. PHPiCalendar reads .ics files just like iCal does, so you can use the iCal export in CC Calendar Pro to create files for PHPiCalendar. Like iCal, PHPiCalendar is a read-only publishing option and, like iCal, it takes each vcal file as its own "calendar" so you can set up filtering in the same way as we described above for Apple's iCal.
