PHP: Get client MAC address

Question

i want to get the client MAC address from an connected socket. usually you can get the IP-address via

$ip = \stream_socket_get_name($socket, true);

is there any chance to get the MAC at the same way? i know all about the facts that the real MAC is only available in a local network and also this hack:

exec("arp $ip");

but i want to avoid to execute an external tool.

volker.

But if it is your app protocol, you can build it in yourself. Put the client MAC into your communication. — raiserle, Dec 08 '20 at 09:01

There is no way, the MAC is not included in the TCP/IP stack and once routed, the client MAC is not visible. MAC = Layer 2

at the end, it is just an HTTP request. – Volker Dec 08 '20 at 09:33
Then it is not possible, unless you provide the browser – raiserle Dec 08 '20 at 09:51
