<?php
//取用户真实ip

$user_ip=$_SERVER["REMOTE_ADDR"];

return $user_ip;

include("geoip.inc");
include("geoipcity.inc");
$gi = geoip_open("yourpath/GeoIP.dat",GEOIP_STANDARD);
$record = geoip_record_by_addr($gi,getUserIP());
//取得城市拼音 例如：Beijing。也可以取经纬度
$city = trim($record->city);
geoip_close($gi);
if($city){
//分析Google Weather Api接口数据
