SPLObjectStorage is definitely a useful class and serves its purpose well. My class offers a bit more flexibility, while SPLObjectStorage offers speed. SPLObjectStorage is FIFO (First In, First Out) and I also dont think it can be implemented? This limits class expansion and functionality. For example, in a future article I was going to add a seeking iterator to my object manager. This would not be possible with SPLObjectStorage. If you know the order of your objects and never need to sort or seek and expect things to return in the same predictable order SPLObjectStorage will be the faster and better option. Like for an active record pattern. If you want flexibility my class is a good alternative :)

Hi Adam, re. “Unfortunately the manual is somewhat lacking.” There is still a vast amount of work to do to fill out the SPL docs but the work is ongoing. Not too long ago we completed at least having some skeleton documentation (classes, methods, etc. listed) added to the manual for all of the available classes but that still leaves a mountain (or mole hill) to climb. More volunteers are always welcome, drop me an email if you are interested at all (whether writing some docs or just being helpful in pointing out what you would like).

Mhh,
I think PHP already has a nice feature for object collections, it´s called SPLObjectStorage.
It´s already really powerfull in the late 5.2.x versions, but with the implementation of the ArrayAccess interface, since version 5.3, its all you need to work with object collections.

I also think, without a concrete benchmark in mind, it´s faster then the example shown above…

Feel free to correct me ;)

I believe when using IteratorAggregate you create the abstract getIterator function used to initialize the iterator object. You could obviously do this transparently in the class and get access to a lot of the duplicate functionality I created. But the IteratorAggregate will create a duplicate of the internal data structure and wont automatically reflect changes.

Since you’re using an internal structure to store objects, it would be simple to implement IteratorAggregate instead of Iterator. The external effects are identical :)

Building an Object Collection Manager with the SPL…

First we are going to do a quick introduction to the interfaces we will be using. After that we will jump right into code and examples. Please keep in mind that the collection class we are going to build is more about demonstrating the capabilities of …
