Hi,
Well I have and do use both, however for what it's worth here's my two
pennies worth. I'd go for PHP as it's extremely flexible and runs on both
Linux and Windows based servers and systems. Although ASP ansd ASP.net can
run on a linux based system it's not terribly stable in my personal
experience.

Although I think the syntax to me was easier to learn for ASP I don't really
like the idea of being walled into mainly windows based systems. I am lucky
enougfh to have a server that runs both well, so to me I pick what language
I thik best solves the problem in the quickest time. Sounds like it would
be a good idea for you to learn to use PHP and MySQL databases together. (A
damn powerful tool!) But on a side note when using databases be aware that
it's always a goodc idea to back up the DB regulalry. I didn't with one of
my sites and when it went down as the whole thing was pulled from the DB I
lost everything:(
Hope this helps.
Merry Xmas

Wayne...
