re: Collection objects in PHP VIEW POST

FULL DISCUSSION
 

As you mentioned arrays are very flexible and offer freedom for developers. It's what makes them good but also very annoying to consume. Personally i feel that only arrays containing a single type is acceptable as return value (see my post on the subject). Iterators are better in most cases.

To be honest i really don't think it's important to implement ArrayAccess on collections (or extend ArrayObject). It's not really bad... but somehow using that bracket syntax feels awkward.

Lack of collections is a pain in the ass in PHP. There is really no convenient way to achieve type safety for collections at the moment (at least one i know of). I create collections all the time by just implementing IteratorAggregate but this means that i do have to create a new class each time i want type safety for a collection.

I really hope we'll see generics sooner rather than later. Also sets and maps.
