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：

}
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 $loc;
}
腾讯的ip分享计划的查询接口连接是：，该连接后面会带有一个get参数searchip1，即searchip1=你要查询的ip地址。采用php向发送http get request，然后获取相应，获得相应结果后，将结果用正则表达式将需要的地理位置信息提取出来就ok了。当然，php发送get请求的方法有很多，我用curl来模拟http请求的方法
curl是php的一个扩展，进行测试之前，先确认php已经加载了curl扩展。打开php配置文件php.ini，搜索 “extension=php_curl.dll”，将其前面的分号（;）去掉，然后重启http服务器，查看phpinfo()，若能看到curl的信 息，说明php扩展curl成功
接下来是新浪网的api接口
新浪的ip查询接口地址是：，该连接后面也带有get参数，参数ip=你要查询的ip地址，format=返回的查询结果格式。为了方便起见，返回的格式采用json，即format=json，因此，php出来扩展curl外，还得扩展json：
/*
*根据新浪ip查询接口获取ip所在地
*/
function getiploc_sina($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。
