For those interested in data access libraries for PHP, the OpenExpedio project is well worth a look at. It will be part of the core for the upcoming release of MODx CMF. I haven’t had a chance to delve into the code to deeply, so any comments about your experiences with this library will be greatly appreciated.

OpenExpedio is our name for open eXtensions to PDO. It’s a light-weight ORB (object-relational bridge) library that works on PHP 4 and 5, and takes advantage of the newly adopted standard for database persistence in PHP 5.1+, PDO. It implements the very simple, but effective Active Record pattern for data access.
