How do websites like www.meebo.com or www.e-messenger.net work? Do they use php to connect to the servers?

I'm interested in how they work, there alot of sites like this and since theres alot I was thinking that it might be easy to make such a site.

they use the xmlhttprequest object to transfer data to and from the clients browser , on the php side they must have some way to communicate with a main script which handles and the connections.

They are somewhat difficult to make if you don't know php or sockets.
