Which framework should i use?

I would like to make a browser based multiplayer game. Not like a flash game, it would be a clicking, managging game. I already started a prototype in OctoberCMS (laravel based) just to test the idea, but it was a quite wrong choice. So now im thinking which framework should i use for this idea. I know PHP but Im not affraid of new languages, and this project is mainly for fun and to learn new stuff. So are there any good framework which suit for this project?
