Wow. MAMP has made me very happy. Frustrated with problems and limitations within Apple's built in Personal Web Sharing, I was looking for a better, more easy to customize webserver. Enter MAMP. Mac Friendly, easy as heck to set up, use, and uninstall (but I doub't you'll want to do that). Amazing freeware at it's best, and so simple everyone who wants to serve php/mysql, or just plain old http should try it. Works well with Tiger.
