I contact my web host a little while ago and they enabled mySQL for my domain. Now I don't know what to do next. I created a simple hello world PHP page and uploaded it and it displayed a blank page.

So... what am I not doing right?

Also, what do I need to install on my computer to debug in place. In other words, how do I install a server with PHP/mySQL capability on my computer?

I have XP Pro.

All help is very much appreciated.
