Many friends want to use php or js to obtain the MAC address of the client. I can tell you that this is impossible, except for the very low permission settings of netizens.

class GetMacAddr{

var $return_array = array(); // Returns a string array with MAC address var $mac_addr;

Function GetMacAddr($os_type){
switch ( strtolower($os_type) ){
case "linux":
$this->forLinux();
break;
case "solaris":
break;
case "unix":
break;
case "aix":
break;
                                                    default:                                                                                              break;


                 $temp_array = array();                                            foreach ( $this->return_array 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->mac_addr = $temp_array[0];
break;

                                                                       ’ ’ s ’ to unset($temp_array’s to be unset($temp_array)--                    return $this->mac_addr;

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



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

}
//方法使用
//$mac = new GetMacAddr(PHP_OS);
//echo $mac->mac_addr;
