Be aware, the connecting client's MAC (Ethernet) address will only be 
available *IF* that client is on the same broadcast domain as your 
PHP/Web server.  If they are on a different broadcast domain, you get 
nothing.

Broadcast domain is best thought of as LAN/VLAN.  In short, the moment 
the packet pops up to layer 3 (ie, router/layer 3 switch) between 
server and client, you're boned.

Suggest you get a good book on the OSI model and read up on Ethernet, 
IP and the layer 4 family (UDP/TCP/etc).
