Since you are already comfortable somewhat with PHP, I suggest you take it in and work on it for a while till you understand the life cycle of a web application. I highly recommend Codeigniter framework - it does a lot of heavy lifting for you.

Taking this route will also help you realise what you like and don't like about PHP. THEN, you will be in a better position to judge if something like django or ruby on rails would suite you better.
