PHP获取服务器的mac地址类

PHP获取服务器的mac地址类，不是客户端的。

<?php 

class GetMacAddr{  
    
        var $return_array = array(); // 返回带有MAC地址的字串数组  
        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:  
                                 $this->forWindows();  
                                 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;  
                        }  

                }
                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;  
        }
     
}   
?>

使用方法

include 'Getmac.php'; 
$mac = new GetMacAddr(PHP_OS);
echo $mac->mac_addr;
