On the Zend Developer Zone there's a new tutorial from Vikram Vaswani looking at combining PHP and the Drizzle database and some of the basics of how they fit together.

Unless you've been completely out of touch with the open source world, you'll have heard of Drizzle, a new database server that's derived from MySQL. [...] Now, while Drizzle is still relatively new, it is quickly gaining attention among open source developers who are interested in experimenting with it, contributing to it, and using it in their projects. And that's where this article comes in.

The tutorial walks you through the installation on your platform of choice (well, of the ones available - OS X, Linux and Solaris) and how to get it configured and installed with your local PHP install. Example scripts showing some of the most common database operations are also included.
