how to open a socket in php

Question

I am completely new to sockets and not that familiar with the concept. I am planning on making a phone application for chatting. now I was told that if you open a socket you can push results (chat entries) to the phone application.

now is this something I can do with fsockopen php function?? and how would I keep the connection open and push data from the database to the application?

Thanks
