PHP through the Taobao API query IP address attribution and other information _php skills

Taobao Company provides a very useful IP geographic information query interface.

Here: http://ip.taobao.com/

TaobaoIPQuery2 This class will greatly simplify the relevant information query.

Class TaobaoIPQuery2 File:

<?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::p Arsejson ($IPInfo);
    The private static function Queryipinfo ($IP) {$query = Http_build_query (An 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);

    Curl_close ($ch);
  return $content;
    private static function Parsejson ($json) {$O = Json_decode ($json, true);

      } if (Version_compare (php_version, ' 5.3.0 ', ' >= ')) {$errorCode = Json_last_error ();

 }

TaobaoIPQuery2.Class.php:

 }

Call:

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

Let's take a look at Tencent API interface

 
 * * According to Tencent IP sharing program address to obtain IP location, more 
 accurate 
/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, ten); 
  curl_setopt ($ch, Curlopt_returntransfer, true); Get Data back 
  $result = curl_exec ($ch); 
  $result = mb_convert_encoding ($result, "Utf-8", "gb2312"); Code conversion, otherwise garbled 
  curl_close ($ch); 
  Preg_match ("@<span> (. *) </span></p> @iU", $result, $ipArray); 
  $loc = $ipArray [1]; 
  return $loc; 

Tencent's IP sharing program's query interface connection is: Http://ip.qq.com/cgi-bin/searchip, the connection will be followed by a get parameter searchip1, that is, searchip1= you want to query the IP address. Using PHP to send HTTP GET request to http://ip.qq.com/cgi-bin/searchip, and then obtain the corresponding results, the results in regular expressions will need to extract the location information is OK. Of course, there are a lot of ways to send get requests in PHP, and I use curl to simulate the way HTTP requests

Curl is an extension of PHP, before testing, verify that PHP has loaded the curl extension. Open the PHP configuration file php.ini, search "Extension=php_curl.dll", remove the semicolon (;) before it, and then restart the HTTP server to view Phpinfo (), and if you can see the curl information, the PHP extension curl successful

Next is Sina's API interface

Sina IP Query Interface address is: http://int.dpool.sina.com.cn/iplookup/iplookup.php, the connection is also followed by get parameters, parameters ip= you want to query the IP address, format= returned the query result format. For convenience, the returned format uses JSON, or Format=json, so that PHP extends the curl outside, and also extends JSON:

 
 * * Based on Sina IP query interface to obtain IP location 
/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, ten); 
  curl_setopt ($ch, Curlopt_returntransfer, true); Get Data back 
  $location = curl_exec ($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; 
} 

Use Getiploc_sina ("183.37.209.57") to get the address location of the IP address.
