Seeing as you know PHP try the Laravel framework (disclaimer: I've never used it but have heard that it's very rails like and I use rails daily because it's very fast and easy to get started with). Use bootstrap for your CSS needs (layout etc is too simple to be true and it will save you a ton of time) and once you have the bones of functionality you want start exploring JS tools for adding a slicker user experience.

If you want to look at something new I can highly recommend the Rails Tutorial by Hartl to bring you up to speed on the basics of web dev with rails, bootstrap and ajax. It also teaches you a bit of git which is a must.
