Undefined index: DTSTART_array

[spalberg]

Hello again, first things first: this time I'm using the latest dev-master ;)

When I try to import a specific ics-file I get the following error:

PHP Notice:  Undefined index: DTSTART_array in /var/www/html/vendor/johngrogg/ics-parser/src/ICal/ICal.php on line 671

The ics-file causing this issue:

Seems like the DTSTART and DTEND keys are "dropped" since the actual datetime-string is in the following line.

• Just ran the parser against your snippet and it works without issue; 13 events in total after recurrence rules have been processed. No errors thrown.
• Your snippet contains 2 events. Can you reduce it to have just the event that is causing the problem on your end?
• Can you upload the iCal file here in case the issue is encoding/line endings?
• What exact code are you using to run the parser against your file?

Thanks

Thanks for the fast response!

I removed the second event (no errors). The resulting file with the first event is still causing errors for me.

issue.txt

I tried opening via your constructor and the filepath:

$ical = new ICal\ICal($filePath, [
    'defaultWeekStart' => 'MO',
]);

and also opening and splitting it myself and calling your constructor with the resulting string array:

$ical = new ICal\ICal(explode("\n", $icsString), [
    'defaultWeekStart' => 'MO',
]);

Both ways result in the given error.

Just to be sure I checked the code of ICal.php against your current commit (07e775f): identical.

• No problem, like to squash these things quickly.
• Some more questions for you as even using what you have uploaded, I still cannot reproduce on my end.

---

• What version of PHP are you running?
  • Must be 5.3.0+
• Are you on a Windows/Linux/Mac machine?
  • Line endings shouldn't be an issue especially as you have provided the exact iCal file.
• Are you able to put a test version online so I can see the issue?
• I don't believe this is timezone related and I have checked using date_default_timezone_set('Europe/Berlin'); which appears to be your timezone

[spalberg]

• I am running PHP 5.6
• Running an archlinux VM on a windows host (php is executed in a docker container inside the VM)
• You are right about the timezone.

Edit: Found the "error". I am running php inside a docker container. I simply recreated the container (used it for a while) and your code runs without errors. I don't exactly know what caused the issue with my "used" container but something sure did... Sorry for taking up your time!
