Accessing the properties... about php-rrule HOT 6 CLOSED

Is this... Normal behavior?

Well yes.

The array access operator is meant to access occurrences by index, not properties of the object. So if you want to access the Nth occurrence, you use $rule[N]. E.g. the 3rd occurrence is $rule[2]. More info on the wiki.

What's happening is when you use $rule['dtstart'], PHP understands $rule[0] due to loose typecasting. $rule[0] is the first occurrence of the set, which incidentally is your dtstart. Note that it could be something else as well, depending on the rule.

RIGHT! Thank you for that clarification, I just couldn't wrap my mind around that... It's one of these days! :)

But then... I might just be a lousy wiki reader, but isn't there a method to get the datetime object of the rule (and not the first occurence) that I didn't see? I'm just so sure I used one in the past, but yeah, it might just be that I misused the array access...

No worries. I'll just keep the issue open for now though, because it might be useful to throw an exception in offsetGet to avoid this kind of confusion. I'll close it once I have added this.

Well I'm not sure. If you mean the DTSTART property, you have getRule() that returns an array of all the properties. So you could use $rrule->getRule()['DTSTART']. Careful though this is not guaranteed to be a datetime object. It will be whatever type you passed to the constructor.

If you know that DTSTART is the first occurence, then by all mean, use $rule[0] to get it as a datetime object.

AH! That's why!

$rrule->getRule()['DTSTART'] returns value passed by constructor! I had some part of the code where I sent a datetime object, and I reused the code somewhere where I instantiated with a Rrule string!

Now it's clear for me! :D

Good! Note that if you pass a RFC String to the constructor, you will get a datetime object for DTSTART. The situations where you would not get a datetime object are if you used an array, with the DTSTART key a string ,e.g. "2017-01-01".

I added checks to offsetGet, now it'll throw an InvalidArgumentException for illegal offset types, which should avoid confusion.
