It really depends what your looking to do. I use Rails and php depending on the project. I would say actually its best to focus on frameworks and Rails is probably one of the better ones out there these days. Django is also interesting. Php frameworks are going through alot of changes right now with no clear winner. So youll have to spend extra time even trying to figure out which one to use whereas with Rails its pretty much the dominant one so all the support in the community goes to it. There are only a few ways you can pass data from one web page to another. Get and Post. Get sends it in the url whereas Post sends it in sort of a hidden way. In the old days post was preferred for more sensitive data so the user wouldnt see things in the url. Also post was and is used to keep the urls cleaner. However with the advent of web services the uses of these have changed somewhat.
