Fatal error on stream example

[dereuromark]

The exact example of the stream output results in

Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 266338320 bytes) in /shared/httpd/app/vendor/jsvrcek/ics/src/CalendarStream.php on line 79

$calendar->setEventsProvider(function () use ($events) {

    $calendarEvents = [];

    foreach ($events as $event) {
        $calendarEvent = new CalendarEvent();

            ->setAllDay($event->date_only)
            ->setSummary($event->title)
            ->setDescription($event->description)

        }

            $geo = new Geo();
            $geo->setLatitude($event->lat);
            $geo->setLongitude($event->lng);
            $calendarEvent->setGeo($geo);
        }

        if ($event->location) {
            $location = new \Jsvrcek\ICS\Model\Description\Location();
            $location->setName($event->location);
            $calendarEvent->addLocation($location);
        }

        $image = $event->image(true);
        if ($image) {
            $calendarEvent->setImage([
                'VALUE' => 'URL',
                'URI' => $image,
            ]);
        }

        $calendarEvents[] = $calendarEvent;
    }

    return $calendarEvents;
});

//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();

Even commenting out the $calendarExport->getStreamObject()->setDoImmediateOutput(true); part does not help.

Hi @dereuromark,

This error means you have used up the amount of memory your setup has allocated to PHP. Running into this issue with this code example is going to be a factor of how big the data is for the calendar events you have, what your php config is, what resources other parts of the php code you are running are taking up, etc. Perhaps you have a very large string in one of your events?

It was a few events only.
