Pim Elshoff has a recent post to his blog looking at a "kickass development environment" he's gotten working on Windows that includes PEAR, some type of version control (git or svn - take your pick), Ant for builds and Jenkins for continuous integration.

Recently I have become quite interested in quality assurance. Not that many things are going wrong for me, but I’d really like to be more certain about the quality of my work. I’ve used some tools to help me achieve just that. In less than two hours you can set up your workspace and have the living daylights automated out of you!

He provides a full guide to getting the full stack set up including the command-line calls you'll need to make, creating a new build file for Ant and setting up the PHP tools (like Phpmd, DocBlox and Pdepend). In the end, you should see something similar to this setup in your Jenkins build.
