Obtain the client mac address:

@ Exec ("arp-a", $ array); // execute the arp-a command and put the result into the array $ array foreach ($ array as $ value) {// put the matching result in an 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 obtained by the client cannot be tested on the local machine. only access from other computers can be used for output.
