Implementing Iterator in PHP 5

There’s a good article on sharepoint about implementing Iterator in PHP
5: http://www.sitepoint.com/article/php5-standard-library/1. I’ve used
it a couple of times now and it’s a great way to treat objects as
collections.

More info about the Standard PHP Library can be found here:
