How to get MAC address of client using PHP?

Question

How can I get MAC Address using PHP or javascript...

Answer 1

echo GetMAC();

function GetMAC(){
    ob_start();
    system('getmac');
    $Content = ob_get_contents();
    ob_clean();
    return substr($Content, strpos($Content,'\\')-20, 17);
}

Above will basically execute the getmac program and parse its console-output, resulting to MAC-address of the server (and/or where ever PHP is installed and running on).
