This package offers a abstraction layer for creating iCalendars. The output will follow RFC 2445 as best as possible.

The following components are supported at this time:

• VCALENDAR
• VEVENT

You can install this package by using Composer. Link to Packagist: https://packagist.org/packages/eluceo/ical

{
    "require": {
        "eluceo/ical": "*"
    }
}

$vCalendar = new \Eluceo\iCal\Component\Calendar('www.example.com');

$vEvent = new \Eluceo\iCal\Component\Event();

$vEvent->setDtStart(new \DateTime('2012-12-24'));
$vEvent->setDtEnd(new \DateTime('2012-12-24'));
$vEvent->setNoTime(true);
$vEvent->setSummary('Christmas');

$vCalendar->addEvent($vEvent);

header('Content-Type: text/calendar; charset=utf-8');
header('Content-Disposition: attachment; filename="cal.ics"');

echo $vCalendar->render();

This package supports three different types of handling timezones:

In the default setting, UTC/GMT will be used as Timezone. The time will be formated as following:

DTSTART:20121224T180000Z

You can use an explicit timezone by calling $vEvent->setUseTimezone(true);. The timezone of your \DateTime object will be used. The output will be as following:

DTSTART;TZID=Europe/Berlin:20121224T180000

You can use local time by calling $vEvent->setUseUtc(false);. The output will be:

DTSTART:20121224T180000
