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)
{
case 'zhongqing':
$currentCityEName = 'chongqing';
break;
case 'shenfang':
$currentCityEName = 'shifang';
break;
case 'chengdou':
$currentCityEName = 'chengdu';
break;
case 'yueshan':
$currentCityEName = 'leshan';
break;
case 'junxian':
$currentCityEName = 'xunxian';
break;
case 'shamen':
$currentCityEName = 'xiamen';
break;
case 'zhangsha':
$currentCityEName = 'changsha';
break;
case 'weili':
$currentCityEName = 'yuli';
break;
case 'zhaoyang':
$currentCityEName = 'chaoyang';
