[PHP] Anyone using SPL Iterators?

[John Holmes]

I've been looking around for some SPL 
(http://www.php.net/manual/en/ref.spl.php) examples and uses, but have only 
found one good article on Sitepoint 
(http://www.sitepoint.com/article/php5-standard-library/).

Is anyone using SPL iterators out there? Any examples you'd like to share 
that you find useful? Iterating through databases or large files, etc? Just 
curious what people are using this for before I write some stuff myself. :)
