Peer-to-Peer PHP,MySQL,Apache

How would one implement a small database on a 5 user peer-to-peer network using php and mysql? I
would be very curious to see examples of how to do
this. I suppose all I would need to know is how to point one's browser to the ip address of the
"server" machine which would have apache, php, and mysql on it... is this very complex to achieve?

Yes, I am a self-taught beginner in PHP and MySQL.

I purchased a small, personal website on a server which provides php and mysql support, and am having reasonable success in getting things to work there.

But I would really like
to find a tutorial or example of how to access
mysql and php on a small peer-to-peer network. I
am guessing that if one of the workstations on the network had a WAMP installation of Apache, MySQL, and PHP, then one would simply have to point their browser, from another workstation,
to the proper IP address, pointing to the workstation with the MySQL database, and then it would function just like someone visiting my personal website. But I am having difficulty envisioning the details of accomplishing this. I did successfully install WAMP (Windows Apache, MySQL, PHP) on my home computer, and I was able to point my browser to localhost and get things to work. How would one point the browser of a workstating on the P2P (peer to peer) at the machine where mysql is installed? How would
one go about learning the proper IP addess of that
machine? I am such a beginner, that any sort of step by step tutorial or example will be greatly appreciated.
