PHP获取MAC地址的函数代码

复制代码 代码如下:
<?php
/**
获取网卡的MAC地址原码；目前支持WIN/LINUX系统
获取机器网卡的物理（MAC）地址
**/
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 = $_SERVER["WINDIR"]."\system32\ipconfig.exe";
if ( is_file($ipconfig) )
@exec($ipconfig." /all", $this->return_array);
else
@exec($_SERVER["WINDIR"]."\system\ipconfig.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;
?>
