根据ip调用新浪api获取城市名并转成拼音

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;
