The Oracle Technology Network has a new article in their "DeployPHP" series posted today - Using the PEAR::MDB2 Database Abstraction Layer with Oracle.

In this installment of the DeployPHP Series, I'll describe how to use MDB2, a high-level database abstraction layer that can be found in PEAR. (Disclaimer: PEAR::MDB2 is currently rated "beta" quality; it has a well-tested and stable code basis, but its API may change over time. For this reason, it cannot be rated as "stable" in the PEAR repository.)

The article, from Tobias Schlitt, starts off with a foundational look at PEAR, database abstraction, and MDB2. Then, it wastes no time getting into the Examples - things such as "Simple Queries", "Advanced Queries", "Managing Databases", and "Schemas".
