Unless the user is on the same LAN as the webserver, you cannot do this. MAC addresses are on the ethernet layer below TCP/IP, and are not included in TCP/IP packets routed off the users local network.
In some environments, it might be possible use to a client-side plugin to allow Javascript access to the MAC address, and transmit that information to the server.
If this is some kind of LAN based web application, you could try getting the MAC address out of the ARP cache. How you do this will depend on the operating system, but under Linux you could parse the output of
arp -n
