Mabe you should look here at the engine description in Zend directory of you PHP source.
Ok, thanks for you summary. I read that and had a look at ZEND_CHANGES.
- [] is overloaded by interface ArrayAccess (this is engine level only count() is missing here) - count() is overloaded by SPL interface Countable.
So basically the question is to whether to 1) add a new function __count 2) add a new interface Countable
After reading all this I'm in favor of the interface as one would then normally use "implements Countable, ArrayAccess" instead of a mix of ArrayAccess and the __count method.
Ok, I shut up now :-) - Chris
