I am developing a multi-user chatting system in php. I know about push and pull, reverse ajax, comet etc. but mostly we have to configure over our server.

However, I can't access my server to install those scripts because I have shared hosting provider.

So after some research I came to know that pusher, pubnub provides api to have push data on browser.

The question is about pubnub, that they are providing channels to send data to clients, but problem is I want to develop multi-user chat in which the data will sent to only one user not like multicasting chat.

As I think one solution is that to make a unique channel per user, so that data will only sent to that user, but this doesn't seems to be efficient. so any other way to implement multi-user chat system with pubnub ?

or any other suggestions that are better ?

  • You typically would create one channel for server to client comms, and another for client to client. http://stackoverflow.com/questions/10459123/pubnub-best-practice-how-to-manage-private-rooms – Makita Aug 11 '12 at 16:16

Also there is a conversation started here which Mikita mentioned on how to create Multiroom Chat Service, likely similar to Facebook Chat, where you are able to join and sit in on multiple chat rooms - PubNub best practice: How to manage private rooms?

EDIT - UPDATED INFO - MARCH 2018

You use of one channel per user is not inefficient. Use as many channels as you like. They cost you nothing more (or less) with respect to how many channels you use.

The pricing plans mentioned above are obsolete. Please review the PubNub Pricing and the Move Away from Device Counting.
