PHP : Best way to push data from server to clients.....?

Question

In my project I need to push some data from server to the client like facebook does, when some updates are performed in the clients profile like somebody writes something in the wall of the client, Facebook automatically push it to the client side.

Currently I am using AJAX to continuously check the DB for the updates. That is not a good practice.

I don't want to depended on the client side for the updates. I want that the server should automatically push the data to the client side when some updates are performed related to the client.

Please suggest some url or sample code to do so......

Thanks in advance.....

Answer 1

You should take a look at the APE Project, which supports multiple variations that are as close to Push as you will get, like long-polling, XHRStreaming and WebSockets.

edit Doing this in just PHP is not the best choice, as it takes up a lot of resources to keep all those connections alive.

you can use node.js: http://nodejs.org/
