One of the people that I met at ZendCon was Joe Stagner, who's been using PHP since before he started work at Microsoft. Joe gave a talk entitled "PHP Rocking in the Windows World" which went down quite well. I'm sad to say that I missed it--I got caught up talking to a bunch of people and lost track of time.

Joe is running a series of PHP-on-Windows webcasts next week on MSDN:

MSDN Webcast: Comparing PHP with ASP.NET

MSDN Webcast: Building and Running PHP Applications on Windows

MSDN Webcast: Extending PHP Applications Using Microsoft Technologies
