TaobaoIPQuery2这个类将极大的简化相关的信息查询。

类 TaobaoIPQuery2 文件：

<?php
/* Usage:
 * $IPInfo = TaobaoIPQuery2::getIPInfo('IPAddress');
 */
Class TaobaoIPQuery2{
 private static $_requestURL = 'http://ip.taobao.com/service/getIpInfo.php';
 public static function getIPInfo($ip){
 $long = ip2long($ip);
 if($long === 0){
 throw new Exception('IP address error', 5);
 }
 $ip=long2ip($long);
 $IPInfo = self::queryIPInfo($ip);
 return self::parseJSON($IPInfo);
 }
 
 private static function queryIPInfo($ip){
 $query = http_build_query(array('ip'=>$ip));
 $ch = curl_init();
 $options = array(
 CURLOPT_URL => sprintf('%s?%s', self::$_requestURL, $query),
 CURLOPT_RETURNTRANSFER => true,
 CURLOPT_AUTOREFERER => false,
 CURLOPT_FOLLOWLOCATION => false,
 CURLOPT_HEADER => false,

 }
 }
 throw new Exception('JSON parse error', 5);
 }
 
 private static $_JSONParseError = array(

 );
}

TaobaoIPQuery2.Class.php：

<?php

}

调用：

$ip = $_SERVER["REMOTE_ADDR"];
$ipquery = new taobaoIPQuery($ip);
$region = $ipquery->get_region();
$country = $ipquery->get_country();
$city = $ipquery->get_city();

我们再来看个腾讯api接口的

/* 
 *根据腾讯IP分享计划的地址获取IP所在地，比较精确 
 */ 
function getIPLoc_QQ($queryIP){ 
 $url = 'http://ip.qq.com/cgi-bin/searchip?searchip1='.$queryIP; 
 $ch = curl_init($url); 
 curl_setopt($ch,CURLOPT_ENCODING ,'gb2312'); 
 curl_setopt($ch, CURLOPT_TIMEOUT, 10); 
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, true) ; // 获取数据返回 
 $result = curl_exec($ch); 
 $result = mb_convert_encoding($result, "utf-8", "gb2312"); // 编码转换，否则乱码 
 curl_close($ch); 
 preg_match("@<span>(.*)</span></p>@iU",$result,$ipArray); 
 $loc = $ipArray[1]; 
 return $loc; 
} 

腾讯的IP分享计划的查询接口连接是：http://ip.qq.com/cgi-bin/searchip，该连接后面会带有一个get参数searchip1，即searchip1=你要查询的IP地址。采用PHP向http://ip.qq.com/cgi-bin/searchip发送http get request，然后获取相应，获得相应结果后，将结果用正则表达式将需要的地理位置信息提取出来就OK了。当然，PHP发送get请求的方法有很多，我用curl来模拟http请求的方法

Curl是PHP的一个扩展，进行测试之前，先确认PHP已经加载了curl扩展。打开PHP配置文件php.ini，搜索 “extension=php_curl.dll”，将其前面的分号（;）去掉，然后重启HTTP服务器，查看phpinfo()，若能看到curl的信 息，说明PHP扩展curl成功

接下来是新浪网的API接口

新浪的IP查询接口地址是：http://int.dpool.sina.com.cn/iplookup/iplookup.php，该连接后面也带有get参数，参数ip=你要查询的IP地址，format=返回的查询结果格式。为了方便起见，返回的格式采用json，即format=json，因此，PHP出来扩展curl外，还得扩展json：

/* 
 *根据新浪IP查询接口获取IP所在地 
 */ 
function getIPLoc_sina($queryIP){ 
 $url = 'http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip='.$queryIP; 
 $ch = curl_init($url); 
 //curl_setopt($ch,CURLOPT_ENCODING ,'utf8'); 
 curl_setopt($ch, CURLOPT_TIMEOUT, 10); 
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, true) ; // 获取数据返回 
 $location = curl_exec($ch); 
 $location = json_decode($location); 
 curl_close($ch); 
 
 $loc = ""; 
 if($location===FALSE) return ""; 
 if (emptyempty($location->desc)) { 
 $loc = $location->province.$location->city.$location->district.$location->isp; 
 }else{ 
 $loc = $location->desc; 
 } 
 return $loc; 
} 

使用getIPLoc_sina("183.37.209.57")即可得到IP地址所在的地址位置。
