PHP gets the client mac address program code_PHP tutorial

WBOYOriginal: 2016-07-13 10:46:501400browse

The mac address is the network card address. Generally, the user's mac address cannot be obtained. Because of security restrictions on the browser, it is almost impossible to obtain it. Here are two pieces of code for everyone to play with.

Example 1

PHP code:

代码如下

复制代码

@exec("arp -a",$array); //执行arp -a命令，结果放到数组$array中
echo "

";

  print_r($array); //打印获取的数组

  

  foreach($array as $value)

  {

      if( //匹配结果放到数组$mac_array

      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; //输出客户端MAC

?>

Example 2

代码如下

复制代码

class MacAddr
{
    public $returnArray = array();
    public $macAddr;

    function __contruct($os_type=null){
        if(is_null($os_type)) $os_type = PHP_OS;
        switch (strtolower($os_type)){
        case "linux":
            $this->forLinux();
            break;
        case "solaris":
            break;
        case "unix":
            break;
        case "aix":
            break;
        default:
            $this->forWindows();
            break;
        }
        $temp_array = array();
        foreach($this->returnArray as $value ){
            if(preg_match("/[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f]/i", $value, $temp_array)){
                $this->macAddr = $temp_array[0];
                break;
            }
        }
        unset($temp_array);
        return $this->macAddr;
    }

    function forWindows(){
        @exec("ipconfig /all", $this->returnArray);
        if($this->returnArray)
            return $this->returnArray;
        else{
            $ipconfig = $_SERVER["WINDIR"]."system32ipconfig.exe";
            if (is_file($ipconfig))
                @exec($ipconfig." /all", $this->returnArray);
            else
                @exec($_SERVER["WINDIR"]."systemipconfig.exe /all", $this->returnArray);
            return $this->returnArray;
        }
    }

    function forLinux(){
        @exec("ifconfig -a", $this->returnArray);
        return $this->returnArray;
    }
}

$mac = new MacAddr(PHP_OS);
echo $mac->macAddr;
echo "
";

// Get client
// linux
$command = "arp -a {$_SERVER['REMOTE_ADDR']}";
echo $command;
echo "
";
$result=`{$command}`;

// windows
$command = "nbtstat -a {$_SERVER['REMOTE_ADDR']}";
echo $command;
echo "
";
$result=`{$command}`;
print_r($result);
?>

There is no big problem in getting the server-side logic, but there may be permission issues.
When obtaining the client, it may be slow, and the execution of the arp/nbstat command will be slow.
