I have a windows server 2003 with ISS 7.0. There runs 2 sites with simple php, which I have installed easily. (C:/Program Files/PHP)
Now I install XAMPP for MYSQL and XAMPP installed a second (inactive) PHP (C:/XAMPP/PHP).
How to change from my installed PHP to XAMPP PHP (It's newer and a few extensions I wanna use it's in there allready) ?
