Greetings,

I'm wanting to learn how to use PHP to check for things like how phpBB or PostNuke do during installation.

For the PHP stuff, I would imagine that I'd use fread() (or a combination of functions like that) to check for a php.ini, then use it to determine the values of some things like version and version and gd. Am I on the right track here?

I also want to be able to check for MySQL versions and such. I don't have a clue as to how to do that. Could I get a point in the right direction for this?

Thanks!
Bill
