pdo-x is a data access library for PHP5. It is intended to provide a lightweight, intuitive wrapper for the PDO database library included in PHP since version 5.1. The pdo-x implementation is, in some ways, similar to the Active Record pattern or the Data Access Object pattern, but at currently less than 40kb in three core files, it leaves less of a footprint than many other implementations. Because it wraps the PDO library, it presents a single, consistent API for accessing different types of databases.
