I already have Apache 2.2, PHP 5.2.10 and MYSQL 5.1 installed on my laptop and they seem to be working well. However, when I use an xmlHttpRequest (Ajax) and in the request.open specify that a .php app should be invoked, I can't get the php app launched via localhost. I've seen others experiencing the same problem and the most common proposed solution is to use xampp.
Should I uninstall Apache, PHP, and MYSQL first? Certainly I don't need 2 copies of the software. It took me quite a while to get all 3 pieces working properly. However, if it is better to delete them before installing xampp, then I would certainly do so.
Any guidance is greatly appreciated.
Thanks
