Right now my favored web development is with PHP and MySQL, but I've thought about going a bit more light weight on my web servers. I've already switched from Apache to lighttpd, but now I'd like to go after the database with a lightweight solution, and SQLite looks like a nice little database. Does anyone here have any experiance with SQLite in this area? Where there any "must have" features that were missing compared to MySQL? Did is scale okay(at least as well as MySQL)?
