How can I get the MAC and the IP address of a connected client in PHP?

Question

I need to know the MAC and the IP address of the connect clients, how can I do this in PHP?

Answer 1

Perhaps getting the Mac address is not the best approach for verifying a client's machine over the internet. Consider using a token instead which is stored in the client's browser by an administrator's login.

Therefore the client can only have this token if the administrator grants it to them through their browser. If the token is not present or valid then the client's machine is invalid.
