I am currently running XAMPP (basic package) version 1.6.7 which has PHP 5.2.6. In order to run a recent upgrade of a software package I need to be on php 5.3. I'm not sure how to do this upgrade. I've googled it and seen people say that you just copy the unzipped version of PHP into the /xampp/php directory but I didn't want to break anything. Can someone please confirm or deny that this is correct? Has anyone reading this post done this sort of thing before?
