Php $\u服务器['；远程地址]为每个用户返回相同的ip

我正在尝试获取访问者的ip地址，但我无法这样做。我试图从

$\u服务器['REMOTE\u ADDR']

获取访问者ip地址，但它为每个访问者返回相同的ip

我从不同的论坛上获得了几个代码，用于获取访问者的ip地址，但运气不好

下面是我尝试的代码

if ($_SERVER['HTTP_CLIENT_IP'])
        $ipaddress = $_SERVER['HTTP_CLIENT_IP'];
    else if($_SERVER['HTTP_X_FORWARDED_FOR'])
        $ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
    else if($_SERVER['HTTP_X_FORWARDED'])
        $ipaddress = $_SERVER['HTTP_X_FORWARDED'];
    else if($_SERVER['HTTP_FORWARDED_FOR'])
        $ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
    else if($_SERVER['HTTP_FORWARDED'])
        $ipaddress = $_SERVER['HTTP_FORWARDED'];
    else if($_SERVER['REMOTE_ADDR'])
        $ipaddress = $_SERVER['REMOTE_ADDR'];

还有以下几点

if (getenv('HTTP_CLIENT_IP'))
        $ipaddress = getenv('HTTP_CLIENT_IP');
    else if(getenv('HTTP_X_FORWARDED_FOR'))
        $ipaddress = getenv('HTTP_X_FORWARDED_FOR');
    else if(getenv('HTTP_X_FORWARDED'))
        $ipaddress = getenv('HTTP_X_FORWARDED');
    else if(getenv('HTTP_FORWARDED_FOR'))
        $ipaddress = getenv('HTTP_FORWARDED_FOR');
    else if(getenv('HTTP_FORWARDED'))
        $ipaddress = getenv('HTTP_FORWARDED');
    else if(getenv('REMOTE_ADDR'))
        $ipaddress = getenv('REMOTE_ADDR');

有人能告诉我有什么问题吗？服务器上是否存在导致此问题的任何配置

或者有什么代码我应该试试吗？

所有用户都在同一个代理后面？您的服务器在负载平衡器/反向代理后面吗…？那么你可能会一直看到它的IP。该代理是否也将原始IP转发给您取决于其设置，请查阅其文档。您能确定它是什么IP地址吗？是公共广播吗？
