SirCastor is correct. You have to turn on personal web sharing and install the php from entropy and the mysql from mysql.com. Then you can go to localhost and see your php enabled web files locally. its pretty darn straightforward compared to setting it up on win or linux - but you still have to jump through some hoops. familiarity with the command line, chown, chmod commands, and knowing where osx puts things is very useful! dang it someday I will write a tutorial - the mac is so powerful most people have no idea.
