Computername abrufen.

Question

Ich baue eine Website für ein Unternehmen, das über eine Software verfügt, die auf dem Computer registriert ist, und verwendet den Computernamen und den Benutzernamen des PCs.Wie kann ich diese Werte abrufen, ohne dass der Benutzer es ausfüllen muss?

Ich verwende cundesigniter, wenn das hilft

Answer 1

You can't. All PHP will ever see of the user's machine is the IP address, from which you MAY be able to do a reverse lookup and get a hostname. But this hostname is not likely to be the actual machine's name. Ditto for the user's client-side username. A website has no business knowing how a user logged into their local machine.

Answer 2

If everything happens on the same local network, you could use the server machine to lookup the mac address corresponding to the IP of the visitor with something like that:

/**
 * Returns MAC-address (Ethernet 2-level in OSI model address)
 * @param string $ip Address to search MAC for. If not set, IP-address from constructor'll be used
 * @return mixed
 */
public function getMAC($ip=null)
{
    if((!$ip && !$this->sCurrentIP) || !$this->_arp_allowed())
    {
        return null;
    }
    $ip=$ip?$ip:$this->sCurrentIP;
    $rgMatches=array();
    if(PHP_OS=='WINNT')
    {
       exec("arp -a", $rgResult);
       $sMacTemplate="/[\d|A-F]{2}\-[\d|A-F]{2}\-[\d|A-F]{2}\-[\d|A-F]{2}\-[\d|A-F]{2}\-[\d|A-F]{2}/i";
       foreach($rgResult as $key=>$value)
       {
          if (strpos($value, $ip)!==FALSE)
          {
             preg_match($sMacTemplate, $value, $rgMatches);
             break;
          }
       };
    }
    else
    {
       exec("arp -a | grep $ip", $rgResult);
       if(count($rgResult))
       {
           $sMacTemplate="/[\d|A-F]{2}\:[\d|A-F]{2}\:[\d|A-F]{2}\:[\d|A-F]{2}\:[\d|A-F]{2}\:[\d|A-F]{2}/i";
           preg_match($sMacTemplate, $rgResult[0], $rgMatches);
       }
    }
    return count($rgMatches)?$rgMatches[0]:null;
}
