根据ip获取地址的几种方法
1.调用新浪IP地址库
<script type="text/javascript" src="js/jquery.js">
</script> <script type="text/javascript" src="js/jquery.cityselect.js">
</script> <script type="text/javascript" src="http://int.dpool.sina.com.cn/iplookup/iplookup.php? format=js"></script>
我们先载入jquery库和cityselect城市下拉插件，然后调用新浪的IP地址库，并以js的形式返回，当然如果你想查询某一指定IP所在的城市信息可以使用接口地址
如：http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip=123.123.123.123，将参数ip值换成指定的IP地址即可。
本地使用：
var myprovince = remote_ip_info['province'];
var mycity = remote_ip_info['city']
var mydistrict = remote_ip_info['district'];
$(function(){
$("#city_1").citySelect({ prov:myprovince, city:mycity });
});
HTML代码：
<h3>调用新浪IP库接口</h3>
<p>您所在的城市是：<script>document.write(myprovince+' '+mycity);</script></p>
<div id="city_1"> <select class="prov"></select> <select class="city"></select>
</div>
2、使用淘宝的ip地址库
淘宝也提供了比较权威的IP地址库，
调用地址：http://ip.taobao.com/service/getIpInfo.php?ip=123.123.123.123，返回对应IP的省市相关信息。
$(function(){
$.getJSON("getTaoIP.php",function(json){
var myprovince2 = json.data.region;
var mycity2 = json.data.city;
$("#city_2").html("您所在的城市是："+myprovince2+mycity2);
});
});
getTaoIP.php用来获取淘宝的对应IP的省市信息，返回的是json格式的数据。
$ip = get_client_ip(); //获取当前用户的ip $url = "http://ip.taobao.com/service/getIpInfo.php?ip=".$ip; $data = file_get_contents($url); //调用淘宝接口获取信息 echo $data;
get_client_ip()用来获取本地用户的IP地址。
//获取用户真实IP function get_client_ip() { if (getenv("HTTP_CLIENT_IP") && strcasecmp(getenv("HTTP_CLIENT_IP"), "unknown")) $ip = getenv("HTTP_CLIENT_IP"); else if (getenv("HTTP_X_FORWARDED_FOR") && strcasecmp(getenv("HTTP_X_FORWARDED_FOR"), "unknown")) $ip = getenv("HTTP_X_FORWARDED_FOR"); else if (getenv("REMOTE_ADDR") && strcasecmp(getenv("REMOTE_ADDR"), "unknown")) $ip = getenv("REMOTE_ADDR"); else if (isset ($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], "unknown")) $ip = $_SERVER['REMOTE_ADDR']; else $ip = "unknown"; return ($ip); }

数据表结构
DROP TABLE IF EXISTS `think_ipdb`;
CREATE TABLE `think_ipdb` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`ip` varchar(30) DEFAULT NULL,
`country` varchar(50) DEFAULT NULL,
`province` varchar(30) DEFAULT NULL,
`city` varchar(30) DEFAULT NULL,
`district` varchar(30) DEFAULT NULL,
`isp` varchar(50) DEFAULT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `ip` (`ip`) USING BTREE
) ENGINE=MyISAM AUTO_INCREMENT=24780 DEFAULT CHARSET=utf8 COMMENT='本地 IP地址库';
调用示例
$think_ipdb = M('think_ipdb',null,C('UC_DB_DSN')); // 实例化User对象 $city = $this->_getLocalDbIp($think_ipdb,$value['ip']);
类方法
/** * 获取本地ip库信息 * @param type $db * @param type $ip */
private function _getLocalDbIp($db,$ip) {
if(empty($ip)){ return null; } $tmp = $db->where(array('ip'=>$ip))->find(); if(empty($tmp)){ $address = getAddressFromIp($ip); if(!empty($address)){ $address['ip'] = $ip; $db->add($address); return $address['city']; }else{ return null; } }else{ $city = $tmp['city']; } }
通用函数
//根据ip地址获取地址信息
function getAddressFromIp($ip){ $urlTaobao = 'http://ip.taobao.com/service/getIpInfo.php?ip='.$ip; $urlSina = 'http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip='.$ip; $json = file_get_contents($urlTaobao); $jsonDecode = json_decode($json); if($jsonDecode->code==0){//如果取不到就去取新浪的 $data['country'] = $jsonDecode->data->country; $data['province'] = $jsonDecode->data->region; $data['city'] = $jsonDecode->data->city; $data['isp'] = $jsonDecode->data->isp; return $data; }else{ $json = file_get_contents($urlSina); $jsonDecode = json_decode($json); $data['country'] = $jsonDecode->country; $data['province'] = $jsonDecode->province; $data['city'] = $jsonDecode->city; $data['isp'] = $jsonDecode->isp; $data['district'] = $jsonDecode->district; return $data; } } //根据ip地质获取城市名 function getCityFromIp($ip){ $data = getAddressFromIp($ip); return $data['city']; }
