PHP is very good for little, dirty projects coded in a weekend, but also for big, long-running projects (well, maybe Java and Rails are better for that). Facebook, Yahoo! and lately (at least, looks like) twitter (that's just a guess after seeing their server-status pages) do use PHP. I do, also. You can build huge projects using a self-made (or external maintained) abstraction structure fitting your needs (database, data clustering, middleware). Or just a countdown page with the days before the next party (?). And, in both examples, it wouldn't be slower to code things with PHP than with RoR.
