As far as I know PHP is still very active and a great choice for new projects. Lots of new projects get started every day in PHP, the language and tools are still in active development as well as frameworks like Symfony for example.

Sure there's lots of legacy crap including WordPress, but there's also no reason not to use it. Just because people wrote a lot of crappy stuff in PHP doesn't mean it can only be used to make crappy stuff. It's very much possible without a lot of trouble to create solid, good performing, easy to develop and maintain applications in PHP.
