php read MAC address_PHP tutorial

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 )

                        @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);
