嗨,我正在尝试获取访问我们内部门户的机器的本地 IP 地址,我需要 IP 192.168.xx.xx,我尝试使用可能的解决方案,例如

$myIp = getHostByName(getHostName());    
$_SERVER['REMOTE_ADDR']
$_SERVER['REMOTE_HOST']

function getLocalIP(){
exec("ipconfig /all", $output);
foreach($output as $line){
if (preg_match("/(.*)IPv4 Address(.*)/", $line)){
$ip = $line;
$ip = str_replace("IPv4 Address. . . . . . . . . . . :","",$ip);
$ip = str_replace("(Preferred)","",$ip);
}
}
return $ip;
}

甚至还有一些来自引用的解决方案

How do I get the local IP address of the server using PHP? , how to get local computer ip address in php , Get Local Machine IP Address in PHP

但是没有任何方法可以得到所需的解决方案?有什么建议吗?

最佳答案

通常,您将无法检索位于 NAT 路由器/防火墙后面的任何计算机的本地 ip 地址,尤其是在服务器上运行的 PHP 时尤其如此,因此上面的代码会找到服务器的ip。

但是,您可以使用 Javascript 和 webRTC 中的一项功能来显示门户访问者的本地 IP 地址。如果需要,可以使用 Ajax 将其结果传递给 PHP。几周前我在调查连接问题时发现了这一点——我访问的一个站点显示了我的公共(public)和本地 IP 地址。在查看源代码并进行进一步研究后,我将以下小函数放在一起 - 也许它可能有用。

<?php
