Present data get from tcp on webpage without refreshing entire page?

My php script communicates over TCP with C server, is there a way to present data obtained from the server while it does not refresh the entire page开发者_StackOverflow, so the data refer to a ajax script?

Yes, Ajax or comet is the answer.

(the references to C, C++ and TCP are irrelevant).

But since you've already answered your own question - what's the problem here?
