I've avoided PHP like the plague so I'll take your word for it. I'd consider using it for a couple of quick & dirty simple pages but for anything more complex I'd definitely use Rails (or Django etc).
As another poster noted, Clojure gives you access to the Java libraries, which is a huge, huge win for Clojure vs most other functional languages but gluing that stuff together is still going to be more work than it's worth if you're not doing something really unusual with your site.
The functional web stack that looks the most promising to me at the moment is the Play framework with Scala. It seems a lot simpler and more manageable than Lift and Scala drops in pretty nicely in place of Java. From what I can tell there are still a lot of rough edges but I think it's a combination worth keeping an eye on.
