display users online in HomePage

How do I display currently online users and other "who is online" stats on my HomePage? is it possible. I'm new to this. some says fetchall could do but i'm newbie and doesn't seem to understand. can anyone help me.

Fetch All is the best way to do it (and honestly, the only one I know of offhand), but it does have a rather steep learning curve. There's a portal.php file included in Fetch All that can be used as an example of how to do the various things Fetch All is capable of - I recommend taking a look at that.

can't understand a thing in fetchall and was wondering if anyone could do it for me or post the code is anyone has it. thank you admin for the reply.
