Question

我试过这个php方法来获取ip地址，但它提供了错误的输出。常规方法

 <?php     echo $_SERVER['REMOTE_ADDR'];   ?>

未提供适当的输出。当我使用这种方法时，我得到像

这样的输出

IP地址：＆＃39; :: 1＆＃39;

我的剧本有什么问题吗？还提供了有关在数据库中存储这些IP地址的详细信息提前致谢

Answer 1

':: 1'表示它是您的本地主机IP地址。

:: 1 == 127.0.0.1

你也可以尝试这个。

$ip=$_SERVER['REMOTE_ADDR'];
echo "IP address= $ip";

如果您的应用程序托管在您尝试请求的同一台计算机上，它将始终返回“:: 1”，这意味着LocalHost。否则它将返回客户端IP地址。

以下是一些示例代码

 if (!empty($_SERVER['HTTP_CLIENT_IP'])) {
    $ip = $_SERVER['HTTP_CLIENT_IP'];
} elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
    $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
} else {
    $ip = $_SERVER['REMOTE_ADDR'];
}

您可以使用返回int的ip2long。检查-1或FALSE的返回值，以确保返回有效的IP。

您看到的输出是IPv6中的本地主机。
