How to implement a real fast web chat with PHP?

Has anybody ever wonder why Facebook chat is just so really really fast? even in IE without WebSocket.

Isn\'t

Answer 1

I agree with @joseph-szymborski although it would make sense to start looking at WebSocket solutions which fallback to WebSockets via Flash and/or long-polling.

Here are some relevant SO questions:

• How to implement facebook like notification on cakephp? - PHP/jQuery
• ajax Push system - PHP/Ajax
• Apache with Comet Support - the question itself is very good.
• PHP Jquery: chat system, what is the Ideal framework for this? - relevant to your question.

If you want to work with PHP or are on shared hosting then I'd recommend looking at a hosted realtime web solution.
