when a user visit my website, it's easy to get the ip address of the
user, but i think IP address is not as stable as mac address, so I
hope I can get the mac address of the user according to its IP
address, is it possible? thanks

Well, if the visitor uses DHCP, then his IP will change at some point, so one cannot
tell the MAC if one knows the IP...however, there are tools like wireshark that can help you
with MAC's.
