Get the client MAC address:

@exec ("Arp-a", $array); Executes the ARP-A command, putting the result into the array $array in the        foreach ($array as $value) {            //Match result placed in the array $mac_array            if (Strpos ($value, $_server[ "REMOTE_ADDR"]) && Preg_match ("/(:?? [ 0-9a-f]{2}[:-]) {5}[0-9a-f]{2}/i ", $value, $mac _array)) {                $mac = $mac _array[0];                break;            }        }        Echo $mac;

Note: The Mac acquired by the client cannot be tested natively and can only be exported with a different computer access
