Server language

I usually use node.js for my server language, and probably varies from each person. I know php has been around a while and has more support with it. Node is faster and handles multiple tasks, whereas php handles one at a time. So it comes down to what type of app you're going to build. Php seems easier to write and less lines of code, but node can be too with express. Correct me if I'm wrong, but isn't that why node is a part of javascript frameworks? Especially for ecommerce sites. C sharp is great but overkill for simple websites. Kind of like putting a hemi in a motorcycle.
