网卡地址有什么用处？

php执行的时候,都是在服务器端,所以客户端取来的也属于服务器的信息

比如WIN下:
<?php
@exec("ipconfig /all",$array);
for($Tmpa;$Tmpa<count($array);$Tmpa++){
if(eregi("Physical",$array[$Tmpa])){
$getstr=explode(":",$array[$Tmpa]);
echo $getstr[1];
}
}
?>

[是是非非]

无法实现～
现在客户端一般都是用路由上网，用ARP的方法也没用

除非你让客户端强制安装一个ActiveX插件
但是除了IE谁都不支持

[broadury]

似乎不可以吧？

什么叫网卡地址？

[lastfiend]

nic地址
UP,我也想知道
这样以后程序安全得多

[-神仙-]

其实改mac地址比改ip容易
