zhangjingyu 一、通过服务器配置获取IP地址 展开讲讲
使用$_SERVER超全局变量 2
$_SERVER['SERVER_ADDR']：直接获取服务器的IP地址，适用于大多数情况3。
$_SERVER['REMOTE_ADDR']：获取客户端（浏览器）的IP地址，需注意代理服务器可能返回伪造IP6。
使用gethostbyname函数 2 .. (2025-12-12 09:21) 查看本帖

$hostname = gethostname();
$ip = gethostbyname($hostname);

function getip() {
    if (getenv("HTTP_CLIENT_IP") && strcasecmp(getenv("HTTP_CLIENT_IP") , "unknown")) {
        $ip = getenv("HTTP_CLIENT_IP");
    } else if (getenv("HTTP_X_FORWARDED_FOR") && strcasecmp(getenv("HTTP_X_FORWARDED_FOR") , "unknown")) {
        $ip = getenv("HTTP_X_FORWARDED_FOR");
    } else if (getenv("REMOTE_ADDR") && strcasecmp(getenv("REMOTE_ADDR") , "unknown")) {
        $ip = getenv("REMOTE_ADDR");
    } else if (isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], "unknown")) {
        $ip = $_SERVER['REMOTE_ADDR'];
    } else {
        $ip = "unknown";
