使用PHP获取用户真实的IP地址 [英] Getting Users Real IP address using PHP

问题描述

即使他们使用像hidemyass.com这样的代理网站，我想从我网站上的用户那里获得真实的IP地址

I want to get the real IP address from users going on my site even if they use a proxy website like hidemyass.com

这是我的代码和认为它有效，但我测试了它并没有

This is the code I have and thought it worked but I tested it and it doesn't

<?php
function getRealIpAddr()
{
    if (!empty($_SERVER['HTTP_CLIENT_IP']))   //check ip from share internet
    {
      $ip=$_SERVER['HTTP_CLIENT_IP'];
    }
    elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))   //to check ip is pass from proxy
    {
      $ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
    }
    else
    {
      $ip=$_SERVER['REMOTE_ADDR'];
    }
    return $ip;
}
?>

我认为这段代码可行，但代理仍然绕过它。

I thought this code would work but proxy still bypass it.

提前致谢。

推荐答案

如果代理人不想告诉你，没有保证获得真实IP地址的方法它（以及任何真正的匿名代理不会）。

There is no guaranteed way to get a "real" IP address, if the proxy doesn't want to tell you about it (and any true anonymous proxy won't).
