The eluceo/iCal package offers an abstraction layer for creating iCalendars. You can easily create iCal files by using PHP objects instead of typing your *.ics file by hand. The output will follow RFC 5545 as best as possible.

The classes within this package are grouped into two namespaces:

  • The Domain contains the information about the events.
  • The Presentation contains the transformation from Domain into a *.ics file.

To create a calendar, the first step will be to create the corresponding domain objects. Then these objects can be transformed into a iCalendar PHP representation, which can be cast to string.

Empty event

In this very basic example, that renders an empty event. You will learn how to create an event domain object, how to add it to a calendar and how to transform it to a iCalendar component.

1. Create an event domain entity

$event = new \Eluceo\iCal\Domain\Entity\Event();

2. Create a calendar domain entity

$calendar = new \Eluceo\iCal\Domain\Entity\Calendar([$event]);

3. Transform calendar domain object into a presentation object

$iCalendarComponent = (new \Eluceo\iCal\Presentation\Factory\CalendarFactory())->createCalendar($calendar);

4. a) Save to file

file_put_contents('calendar.ics', (string) $iCalendarComponent);

4. b) Send via HTTP

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

echo $iCalendarComponent;

Full example

The following example will create a single day event with a summary and a description. More examples can be found in the examples/ folder.


require_once __DIR__ . '/../vendor/autoload.php';

// 1. Create Event domain entity
$event = (new Eluceo\iCal\Domain\Entity\Event())
    ->setSummary('Christmas Eve')
    ->setDescription('Lorem Ipsum Dolor...')
        new Eluceo\iCal\Domain\ValueObject\SingleDay(
            new Eluceo\iCal\Domain\ValueObject\Date(
                \DateTimeImmutable::createFromFormat('Y-m-d', '2030-12-24')

// 2. Create Calendar domain entity
$calendar = new Eluceo\iCal\Domain\Entity\Calendar([$event]);

// 3. Transform domain entity into an iCalendar component
$componentFactory = new Eluceo\iCal\Presentation\Factory\CalendarFactory();
$calendarComponent = $componentFactory->createCalendar($calendar);

// 4. Set headers
header('Content-Type: text/calendar; charset=utf-8');
header('Content-Disposition: attachment; filename="cal.ics"');

// 5. Output
echo $calendarComponent;
