In this new post to his blog Brian Swan talks about a tool that's been released by the IIS Team at Microsoft to make it even simpler to run multiple versions of PHP under IIS - the PHP Manager.

Not only does the PHP Manager make it a no-brainer to run different PHP versions side-by-side on IIS, it makes it easy to register PHP with IIS, configure various PHP settings, enable/disable PHP extensions, remotely manage PHP configuration via the php.ini file, and check the PHP runtime configuration and environment (i.e. see the output of phpinfo()).

Brian goes through a six step process to use this new tool to set up both PHP 5.2 and PHP 5.3 versions on an IIS server. It's as simple as installing the tool, registering new PHP versions and customizing the configurations. They'd love feedback on the tool so leave them comments here or report bugs here.
