如何使用PHP代码获取IPv4和IPv6地址? [英] How can I get both IPv4 and IPv6 address using PHP code?

问题描述

我有一个向其他服务器发送请求的脚本，但问题是不支持IPv6，因此如果我发送IPv6则给出错误，所以我需要以下两个之一:

I have a script which sends a request to another server but problem is that IPv6 does not supported so if I send IPv6 then give error so i need this one of two:

1. 始终获取IPv4地址 或
2. 同时获取IPv4和IPv6地址

1. Get IPv4 address all time or
2. Get both IPv4 and IPv6 addresses

我使用此代码获取IP地址

function getRealIP()
    {
        if (isset($_SERVER["HTTP_CLIENT_IP"])) {
            $ip = $_SERVER["HTTP_CLIENT_IP"];
        } elseif (isset($_SERVER["HTTP_X_FORWARDED_FOR"])) {
            $ip = $_SERVER["HTTP_X_FORWARDED_FOR"];
        } elseif (isset($_SERVER["HTTP_X_FORWARDED"])) {
            $ip = $_SERVER["HTTP_X_FORWARDED"];
        } elseif (isset($_SERVER["HTTP_FORWARDED_FOR"])) {
            $ip = $_SERVER["HTTP_FORWARDED_FOR"];
        } elseif (isset($_SERVER["HTTP_FORWARDED"])) {
            $ip = $_SERVER["HTTP_FORWARDED"];
        } else {
            $ip = $_SERVER["REMOTE_ADDR"];
        }

        // Strip any secondary IP etc from the IP address
        if (strpos($ip, ',') > 0) {
            $ip = substr($ip, 0, strpos($ip, ','));
        }
        return $ip;
    }

但是此函数仅返回一个IPv地址.如何获得所有时间IPv4或同时获得两个地址?

But this function only returns one IPv address. How can I get all time IPv4 or get both addresses?

推荐答案

您不能.

只有来自请求的IP地址可用.

Only the IP address the request came from is available.

没有可靠的方法来识别路由到同一台计算机的其他IP地址(我的笔记本电脑当前有12个IP地址).

There's no reliable way to identify other IP addresses (my laptop currently has 12 IP addresses) that route to the same computer.
