<?php 

$url = 'http://ip.taobao.com/service/getIpInfo2.php';//淘宝提供的一个ip地址库

$data=array('ip'=>'219.144.202.12');

function curl_post($url, $header=array(), $data=array(), $referer=NULL, $timeout=5){

$json = json_decode($html);



echo $json->data->country.$json->data->area.$json->data->region.$json->data->city;
