获取IP地址信息

<?php
//获取ip
function getip() {
    if (getenv("HTTP_CLIENT_IP") && strcasecmp(getenv("HTTP_CLIENT_IP") , "unknown")) {
        $ip = getenv("HTTP_CLIENT_IP");

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

获取客户端语言

<?php
function GetLang() {
    if (!empty($_SERVER['HTTP_ACCEPT_LANGUAGE'])) {
