php获取客户端ip地址的方法

参考 http://www.nowamagic.net/php/php_GetIP.php

public function getipAction(){

if (getenv("HTTP_CLIENT_IP")

&& strcasecmp(getenv("HTTP_CLIENT_IP"), "unknown"))

$ip = getenv("HTTP_CLIENT_IP");

else if (getenv("HTTP_X_FORWARDED_FOR")

&& strcasecmp(getenv("HTTP_X_FORWARDED_FOR"), "unknown"))

$ip = getenv("HTTP_X_FORWARDED_FOR");

else if (getenv("REMOTE_ADDR")

&& strcasecmp(getenv("REMOTE_ADDR"), "unknown"))

$ip = getenv("REMOTE_ADDR");

else if (isset($_SERVER['REMOTE_ADDR'])

&& $_SERVER['REMOTE_ADDR']

&& strcasecmp($_SERVER['REMOTE_ADDR'], "unknown"))

$ip = $_SERVER['REMOTE_ADDR'];

else

$ip = "unknown";

return $ip;

}

如果本地测试得到的值是127.0.0.1，不用担心，只要发布到服务器上，测试一下就能得到真正的客户端ip。
