Continuing on from the first part of the series looking at the use of Adapter objects, DevShed has posted part two today - using the Adapter objects along with Directory Iterators to integrate with a MySQL database.

Provided that you understand the basic concepts of the adapter pattern, in this final tutorial, I'll show you how to use it in conjunction with the "DirectoryIterator" class, bundled with PHP 5, and with a couple of MySQL wrappers as well.

They jump right in (as was said, assuming you read the previous article) to using the directory iterators and the adapters together to make a class that gets information about the files in a directory. They take this and show a sample use that's then transformed into a class capable of using the same logic on MySQL results.
