ICS

Object-oriented php library for creating (and eventually reading) .ics iCal files., _(*2)

This project does not yet support all functionality of the .ics format.

Installation

Using composer:, _(*3)

composer require jsvrcek/ics

1. Basic Usage

use Jsvrcek\ICS\Model\Calendar;
use Jsvrcek\ICS\Model\CalendarEvent;
use Jsvrcek\ICS\Model\Relationship\Attendee;
use Jsvrcek\ICS\Model\Relationship\Organizer;

use Jsvrcek\ICS\Utility\Formatter;
use Jsvrcek\ICS\CalendarStream;
use Jsvrcek\ICS\CalendarExport;

//setup an event
$eventOne = new CalendarEvent();
$eventOne->setStart(new \DateTime())
    ->setSummary('Family reunion')
    ->setUid('event-uid');

//add an Attendee
$attendee = new Attendee(new Formatter());
$attendee->setValue('moe@example.com')
    ->setName('Moe Smith');
$eventOne->addAttendee($attendee);

//set the Organizer
$organizer = new Organizer(new Formatter());
$organizer->setValue('heidi@example.com')
    ->setName('Heidi Merkell')
    ->setLanguage('de');
$eventOne->setOrganizer($organizer);

//new event
$eventTwo = new CalendarEvent();
$eventTwo->setStart(new \DateTime())
    ->setSummary('Dentist Appointment')
    ->setUid('event-uid');

//setup calendar
$calendar = new Calendar();
$calendar->setProdId('-//My Company//Cool Calendar App//EN')
    ->addEvent($eventOne)
    ->addEvent($eventTwo);

//setup exporter
$calendarExport = new CalendarExport(new CalendarStream, new Formatter());
$calendarExport->addCalendar($calendar);

//output .ics formatted text
echo $calendarExport->getStream();

2. Batch Event Provider

The basic usage example will build the complete .ics string in memory and then echo it all at once. This will use a lot of memory for a large calendar. The following example shows how to make CalendarExport::getStream() output each line of the ics file as it is generated, as well as how to set a provider for building the event list of a calendar in batches during export., _(*4)

use Jsvrcek\ICS\Model\Calendar;
use Jsvrcek\ICS\Model\CalendarEvent;

use Jsvrcek\ICS\Utility\Formatter;
use Jsvrcek\ICS\CalendarStream;
use Jsvrcek\ICS\CalendarExport;

//setup calendar
$calendar = new Calendar();
$calendar->setProdId('-//My Company//Cool Calendar App//EN');

//setup event provider to add events in batches during event iteration in $calendarExport->getStream()
$calendar->setEventsProvider(function ($startKey) use ($myDatabase) {

    //pseudo-code to get a batch of events from database
    $eventDataArray = $myDatabase->getEventsBatch($startKey);

    $events = array();

    foreach ($eventDataArray as $row) {
        $event = new CalendarEvent();
        $event->setStart($row['start_date'])
            ->setSummary($row['summary'])
            ->setUid($row['event_uid']);

        $events[] = $event;
    }

    return $events;
}); 

//setup exporter
$calendarExport = new CalendarExport(new CalendarStream, new Formatter());
$calendarExport->addCalendar($calendar);

//set exporter to send items directly to output instead of storing in memory
$calendarExport->getStreamObject()->setDoImmediateOutput(true);

//output .ics formatted text
echo $calendarExport->getStream();
