The IBM developerWorks website has posted their introduction to getting PHP up and working with the Project Zero development environment.

Project Zero provides an environment for the rapid development of interactive Web applications based on popular Web technologies such as PHP. This tutorial demonstrates how easy it is to get started with Project Zero, from installing the development tools to constructing an Ajax Web 2.0 sample using PHP as the back-end scripting language. Exporting an application is covered on the way, together with examples of debugging and extending a Web 2.0 application.

It walks you through the installation, developing two simple applications with HTML and Javascript and include the Dojo library for extra functionality. You'll have to have an IBM ID (free registration) to check out the tutorial, though.
