Générer un évenement *.ics pour outlook en PHP

Il est maintenant possible de l’utiliser via composer :

"calendar/icsfile": "dev-master"

Salut,

Pour un besoin personnel j’ai du créer cette class PHP qui génère un événement pour Outlook, gmail…
Voici la classe en question :

<?php
/*
 * Variables used in this script:
 * $summary     - text title of the event
 * $dateStart   - the starting date (in seconds since unix epoch)
 * $dateEnd     - the ending date (in seconds since unix epoch)
 * $address     - the event's address
 * $description - text description of the event
 * $filename    - the name of this file for saving (e.g. my-event-name.ics)
 */

Pour l’utiliser voici le code :

 <?php      
 require_once 'vendor/autoload.php';

    use ical\ical;
try {
 
        $ical = new ical();
        $ical->setAddress('Paris');
        $ical->setDateStart('2014-11-21 15:00:00');
        $ical->setDateEnd('2014-11-21 16:00:00');
        $ical->setDescription('wonder description');
        $ical->setSummary('Running');
        $ical->setFilename(uniqid());
        $ical->setHeader();
       
    echo $ical->getICAL();
            
  
        } catch (Exception $exc) {
            echo $exc->getMessage();
