Don't worry about "Extensive support of libraries and frameworks", you don't need it. All web sites I built, large and small, required only two additional components: the DB glue (typically mysql) and UTF support (mbstring). There may be specific situations when you might want to send https requests or use compression, but that's ok, even that is not called "extensive libraries and frameworks". The bottom line is, a good web site has a clean, simple source that doesn't depend on third-party code that much.
