Like the Stack Overflow survey, this one does not distinguish server-side/client-side JavaScript, making it look far more popular than it actually is when considering the data in context of server-side technologies.

If 100% of the servers were running PHP, the results would likely be 50% PHP, 50% JavaScript.

These survey writers need to modify their question, or add another one specifically requesting server-side tech so JS can be accurately compared with server-side only languages.
