淘宝公司提供了一个很好用的IP地理信息查询接口。

在这里:http://ip.taobao.com/

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, $query),
          CURLOPT_RETURNTRANSFER => true,
          CURLOPT_AUTOREFERER => false,
          CURLOPT_FOLLOWLOCATION => false,
          CURLOPT_HEADER => false,
          CURLOPT_TIMEOUT => 3.0,
        );
        curl_setopt_array($ch, $options);
        $content = curl_exec($ch);
        curl_close($ch);
        return $content;
      }

      private static function parseJSON($json){
        $O = json_decode ($json, true);
        if(false === is_null($O)){
          return $O;
        }
        if (version_compare(PHP_VERSION, '5.3.0', '>=')) {
          $errorCode = json_last_error();
          if(isset(self::$_JSONParseError[$errorCode])){
            throw new Exception(self::$_JSONParseError[$errorCode], 5);
          }
        }
        throw new Exception('JSON parse error', 5);
      }

      private static $_JSONParseError = array(
        JSON_ERROR_NONE=>'No error has occurred',  
        JSON_ERROR_DEPTH=>'The maximum stack depth has been exceeded',  
        JSON_ERROR_CTRL_CHAR=>'Control character error, possibly incorrectly encoded',  
        JSON_ERROR_STATE_MISMATCH=>'Invalid or malformed JSON',  
        JSON_ERROR_SYNTAX=>'Syntax error',  
        JSON_ERROR_UTF8=>'Malformed UTF-8 characters, possibly incorrectly encoded',
      );
    }

TaobaoIPQuery2.Class.php：


    <?php
    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, $query),
          CURLOPT_RETURNTRANSFER => true,
          CURLOPT_AUTOREFERER => false,
          CURLOPT_FOLLOWLOCATION => false,
          CURLOPT_HEADER => false,
          CURLOPT_TIMEOUT => 3.0,
        );
        curl_setopt_array($ch, $options);
        $content = curl_exec($ch);
        curl_close($ch);
        return $content;
      }

      private static function parseJSON($json){
        $O = json_decode ($json, true);
        if(false === is_null($O)){
          return $O;
        }
        if (version_compare(PHP_VERSION, '5.3.0', '>=')) {
          $errorCode = json_last_error();
          if(isset(self::$_JSONParseError[$errorCode])){
            throw new Exception(self::$_JSONParseError[$errorCode], 5);
          }
        }
        throw new Exception('JSON parse error', 5);
      }
      private static $_JSONParseError = array(
        JSON_ERROR_NONE=>'No error has occurred',  
        JSON_ERROR_DEPTH=>'The maximum stack depth has been exceeded',  
        JSON_ERROR_CTRL_CHAR=>'Control character error, possibly incorrectly encoded',  
        JSON_ERROR_STATE_MISMATCH=>'Invalid or malformed JSON',  
        JSON_ERROR_SYNTAX=>'Syntax error',  
        JSON_ERROR_UTF8=>'Malformed UTF-8 characters, possibly incorrectly encoded',
      );
    }

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。
