Then knowing who is online is maybe the last of your problems. You have to find a way to send the message to "user B" when "user A" writes something. You absolutely need javascript. You just need to find out how to connect to the server. Have a look at socket.io, and find a php library that supports it. I think it is the easiets way. Be aware that the load on your server will be huge, growing exponentially with the number of online users. You can't escape it, except by using different technologies (XMPP as a protocol, with a javascript client, or using node.js with socket.io, for example) Bye. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I'm basing this on previous posts on forums I've been on, so it might have been fixed now, but I don't know for sure either way. Thanks, Ash http://www.ashleysheridan.co.uk

If you want to have a "super user" who has access to all the sessions, you can use the filesystem functions to read the directory in which the sessions get saved (it depends on the server configuration) or you can implement a session handler to save all the sessions in the database, and give access to that table to one user.
