哦，这个不用写，这个是这样判断的

    if (defined("CHECK_X_FORWARDED_FOR")) {
        @$fullfromhost=$_SERVER["HTTP_X_FORWARDED_FOR"];
        if ($fullfromhost=="") {
            @$fullfromhost=$_SERVER["REMOTE_ADDR"];
            $fromhost=$fullfromhost;
        }
        else {
            $ips = explode(",", $fullfromhost);
            $c = count($ips);
            if ($c > 1) {
                $fromhost = trim($ips[$c - 1]);
                if (isset($proxyIPs) && in_array($fromhost, $proxyIPs)) {
                    $fromhost = $ips[$c - 2];
                } // X-Forwarded-For 里要是没这么多一个就不用了
            } else $fromhost = $fullfromhost;
        }
    }
【 在 fancyrabbit (fancy★岁月静好现世安稳) 的大作中提到: 】
: 哦，然后在下面写
: $proxyIPs = array("127.0.0.1"); // 你的 squid 相对于 webserver 的地址
