Well yes, if you wanted to have a web page or whole site that shows off your highscores, then yes.

BUT, I'd recommend doing one thing at a time. First get your high scores working between database server and wherever your game runs. THEN worry about web pages that show the high scores. Your development will be all the happier for it.

The PHP docs are actually pretty great to be honest though. When you get to that part it shouldn't be too hard to pick-up and learn PHP. I could even post a small script that you can take and copy paste and edit a few parameters and reuse to get whatever data you want to be displayed whereever you want on any PHP generated webpage.

For now though, figure out your MySQL library access from your game side of things.
