Which one is best for server side programming java,php,python,asp?

Answer 1

All questions about "Which one is the best ...?" have the same answer:

It depends. What does it depend on? From the developer and his skill / experience with each language. And the requirements of what will develop. Only in a specific scenario can someone tell you what is best according to their reasoning.

Answer 2

Let me ask you a question. Which meat is the best, pig, cow, lamb, or fish. There isn't a clear answer. It depends on the person and preference, what mood you might be in. It's the same thing with programming languages. There isn't a clear winner, it depends on what you want to get done, and what you prefer.
