On the "Blond R" blog, there's a first posting that shares some of the knowledge that the author has gained from working to get IIS7 installed with MySQL and PHP 5.
As all of us are talking about the new coming Windows Vista, I decided to dedicate my first post to guide you all on how to setup IIS 7 along with MySQL and PHP 5.
He hadn't found a tutorial that covered getting all three working well together, so decided to create his own - complete with screen shots for each step of the way. First, IIS is set up, then PHP, then, finally, the MySQL installation is completed and all three are tied together. All downloads are linked as well to make it even easier to set your system up.
