Not that I haven’t already been running PHP on Windows for years, but there’s hope on the horizon for finally having a stable CGI implementation of PHP under IIS. Check out the FastCGI project, which today released its Technical Preview 2 version. For Zend‘s part, they have a special build of PHP 5.2/Zend Core optimized for FastCGI. I need to crank up a virtual machine to try this on, but in concept it sounds promising.
