Use exec and the extra args to get error codes.
Can you run 'arp' and get what you want from command line?
Can you 'su' to PHP user and *then* run it and get what you want?
If not, you can't do that.
I dunno what 'arp' is gonna give you, but I wouldn't think you'd in
general have access to the MAC address of a visitor hardware... Nor
should you, actually... But if you've got your boxes configured to
let any ol' person run this 'arp' thing and reply with their MAC
addresses, I guess it oughta work...
