In this new post to the PHPMaster.com site today Vito Tardia introduces you to Phing, a tool for making builds and deploying your applications (and it's PHP based!)

Suppose you have a web application that is installed on many hosts. Each installation may have a custom configuration, and the application is still in active development. You need an easy way to deploy new features and bug fixes to all of hosts. [...] In this article I show you how to use this knowledge [from this previous article] to write a boilerplate build file, one that can be customized and reused in your real-world applications. We’ll use Phing’s Subversion tasks to manage the repository and the FileSync extension to synchronize your local installation with a remote server.

He helps you to get the environment set up correctly (installing the needed PEAR packages), create a basic build file with the FTP settings in it and creating a "deploy" target to do the work. He also shows the settings/configuration involved in a "prepare" target that does the SVN work to do some of the pre-push work. Finally, he shows a "release" target that bundles up the files into a package and pushes it up to the server (via FTP).
