Brian Swan has posted a new timeline to his MSDN blog today about the road that Microsoft has traveled with PHP to get to where they are today.

This morning I came across this article on PHPDeveloper.org: Blast from the Past – One Year Ago in PHP. That brief look into the past got me to thinking about what Microsoft has done lately toward PHP interoperability. (By "lately", I mean in the last few years.) And, I’ve been working on a presentation for TechEd in Berlin next month that will, in part, provide a brief overview of Microsoft’s efforts toward PHP interoperability and support. So, I thought I’d share a bit of that summary here

The timeline runs from back in 2006 when PHP and Windows/IIS/SQL Server just wasn't much of an option through the FastCGI and SQL Server driver years and finally rounding out with WinCache, PHP 5.3 improvements for Windows and the Azure SDK for PHP.
