Web Development: unification of different tools

I've been using Php, MySQL, JS and HTML since quite a while now and I'm looking for a different tool to create websites.

I looked around the web to find a one-language or one-tool that unifies all of the server side, database and html, but couldn't find any.

I've thought there could be some language or framework that deals with all of those elements in ONE language.

Is it possible? Do you know of any?
