IPv6

其实这个很简单,只不过我一直想用 ipv6-test 的API做一个获取用户IP地址的东西……无奈JSON获取到的只是本机服务器的IP。算了,不研究了,何况人家提供的widget也挺好用的。谷歌了一下,找到这段代码,可以根据用户环境获取IP地址。

例如IPv6访问 www.shiwo.de 则获取到的是用户的IPv6地址

p.s 前提是网站做了A和AAAA解析

复制代码 代码如下:
function getIP() /*获取客户端IP*/
{
if (@$_SERVER["HTTP_X_FORWARDED_FOR"])
$ip = $_SERVER["HTTP_X_FORWARDED_FOR"];
else if (@$_SERVER["HTTP_CLIENT_IP"])
$ip = $_SERVER["HTTP_CLIENT_IP"];
else if (@$_SERVER["REMOTE_ADDR"])
$ip = $_SERVER["REMOTE_ADDR"];
else if (@getenv("HTTP_X_FORWARDED_FOR"))
$ip = getenv("HTTP_X_FORWARDED_FOR");
else if (@getenv("HTTP_CLIENT_IP"))
$ip = getenv("HTTP_CLIENT_IP");
else if (@getenv("REMOTE_ADDR"))
$ip = getenv("REMOTE_ADDR");
else
$ip = "Unknown";
return $ip;
}
?>
