When I set it up, all I did was put my normal pop server names in.
But as I have said, I could never get the set up to work properly. Single pages were served fine, but as soon as I tried to call another PHP page the system reported an error - one which didn't occur on a web-based server. I wasn't alone in experiencing the problem, but by then it didn't matter. And there were other quirks as well.
But that was 3 or 4 years ago.
Being online these days with high-speed connections means there's not much point in going through all the hassle unless you are doing it professionally (IMO). I always upload my scripts directly and test them there - after all, that's where they need to work.
