PHP和Flex应用程序之间的实时通信

Question

I have a Flex/AIR application communicating with a PHP server application. Recently my client requested real-time-like connectivity between the applications to replace what we currently have; refresh buttons which have to be clicked to refresh data.

So effectively the server needs to push data to the client when something changes. I can write the code that detects when something changes, but I'm not sure about the push side of things.

What's my best option here?

Actually you can push data from the server to the client, when using Flash sockets (which means bypassing the http protocol). If you cannot use sockets you can use things like polling, long polling or http streaming. However it will take a while to do everything by hand, so I suggest looking at a product which already has this features. WebOrb for PHP is one of them, and from what I know is free.
