功能：

1，获取当前IP地址，

2，调用新浪API，获取到当前城市。

3，将中文转换为拼音后跳转。

复制代码 代码如下:

<?php

include './pinyin.php';

//获取当前ip

function getIp(){

$onlineip='';

if(getenv('HTTP_CLIENT_IP')&&strcasecmp(getenv('HTTP_CLIENT_IP'),'unknown')){

$onlineip=getenv('HTTP_CLIENT_IP');

} elseif(getenv('HTTP_X_FORWARDED_FOR')&&strcasecmp(getenv('HTTP_X_FORWARDED_FOR'),'unknown')){

$onlineip=getenv('HTTP_X_FORWARDED_FOR');

} elseif(getenv('REMOTE_ADDR')&&strcasecmp(getenv('REMOTE_ADDR'),'unknown')){

$onlineip=getenv('REMOTE_ADDR');

} elseif(isset($_SERVER['REMOTE_ADDR'])&&$_SERVER['REMOTE_ADDR']&&strcasecmp($_SERVER['REMOTE_ADDR'],'unknown')){

$onlineip=$_SERVER['REMOTE_ADDR'];

}

return $onlineip;

}

//获取城市信息api

function getLocation($ip){

$curl = curl_init();

curl_setopt($curl, CURLOPT_URL, "http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip=".$ip);

curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 30);

$str = curl_exec($curl);

curl_close($curl);

return $str;

}

//当前ip地址

$currentIP = getIp();

//通过当前ip获取信息

$getLocation = getLocation($currentIP);

$currentInfo = json_decode($getLocation, true);

//判断ip是否为有效

if($currentInfo['ret'] == '-1')

{

$currentInfo['city'] = 'unknown';

}

//当前城市中文名

$currentCityName = $currentInfo['city'];

$currentCityEName = $pin->Pinyin("$currentCityName",'UTF8');

//城市拼音多音字

switch($currentCityEName)

{

$currentCityEName = 'chongqing';
