I am a Web Developer in PHP, and also know Javascript and some bit of CSS which is needed for web development. I use Symfony framework to build Websites and Web Application. As now i want to learn new Programming Language, which is best for Web Development(like Ruby, Python), as i have heard about Frameworks like Rails and Django. Which language will be best for Web Development apart from PHP or like PHP?

As others have pointed out, it is impossible to give a definitive answer to your question.To determine what is best in a particular situation you should look atWhat are the important requirements for the site?Response times?Scalability?Concurrent users needing to be handled?What are your developers' skill sets?How will the site be hosted?Do you have to work with an existing code base?Personal preference of the developers/management etc (Not everyone works the same, hence langauge benefits will vary from person to person)Skills available in the current job marketMany more...The language someone will use will depend on how the questions above are answered.
