I want to know Comet. Searching over net I came to know that Comet uses persistent connection. So I want to know is this good with php.Can some one give me example of comet to know the current time. Any help or suggestions will be highly appreciable.

</div>

php isn't an idea language for comet because it's designed for a one shot request->response scenario. What you can do is have a comet server that sits on top of your regular server and pipes non-comet connections directly to the standard server. An example of this is StreamHub.

if you're still set on using php you can read this, but the limitations will become apparent very quickly.
