I installed Apache 2.2, no problem. I installed PHP 5 manually, no problem. I tested a php script that contains phpinfo() by typing http://localhost - it works. However my goal is to have the .php extension integrated into my browser so that a single double-click opens it like I can do with html and flash files. The way it is right now I would have to move the php file and the entire project directory into the work folder configured in Apache. When I do try to double click on a php file in Windows to run it, it simply starts Dreamweaver. How can I change this so that it opens with the browser and Apache/PHP? Sorry if I missed it somewhere in the docs. Thanks
