Markus Poerschke has PHP package that provides an abstraction layer for creating iCalendars:

use Eluceo\iCal\Component\Calendar; use Eluceo\iCal\Component\Event; $vCalendar = new Calendar('www.example.com'); $vCalendar->setName('Example Calendar'); $vCalendar->setTimezone('America/New_York'); $vEvent = new Event(); $vEvent ->setDtStart(new \DateTime('2012-12-24')) ->setDtEnd(new \DateTime('2012-12-24')) ->setNoTime(true) ->setSummary('Christmas'); $vCalendar->addComponent($vEvent); header('Content-Type: text/calendar; charset=utf-8'); header('Content-Disposition: attachment; filename="cal.ics"'); echo $vCalendar->render(); 

The library supports the following iCalendar components:

• VCALENDAR
• VEVENT
• VALARM
• VTIMEZONE

After incorporating it in your application, here’s an example of linking to a calendar:

<a href="webcal://www.example.com/holidays.ics">Subscribe (iCal)</a>
