通过GeoIP获取ip所属地 (国家，城市，时区，邮编，经纬度等)

来源： http://www.phpandstuff.com/articles/geoip-country-lookup-with-php

 

GeoIP + PHP

<?php

    //计时开始
    function utime() {
        $time = explode( " ", microtime() );
        $usec = (double)$time[0];
        $sec = (double)$time[1];
        return $usec + $sec;
    }
    $startTimes = utime();

    // include the php script
    // wget -c http://geolite.maxmind.com/download/geoip/database/GeoLiteCountry/GeoIP.dat.gz
    // gunzip GeoIP.dat.gz
    include("geoip.inc");

    // open the geoip database
    $gi = geoip_open("GeoIP.dat",GEOIP_STANDARD);

    // 获取国家代码
    $country_code = geoip_country_code_by_addr($gi, $_SERVER['REMOTE_ADDR']);
    echo "Your country code is: <strong>$country_code</strong> <br />";

    // 获取国家名称
    $country_name = geoip_country_name_by_addr($gi, $_SERVER['REMOTE_ADDR']);
    echo "Your country name is: <strong>$country_name</strong> <br />";

    // close the database
    geoip_close($gi);

    //运行结束时间
    $endTimes = utime();
    $runTimes = sprintf( '%0.4f', ( $endTimes - $startTimes ) );
    echo "Processed in " . $runTimes . "second.";
?>

 

注：在本地测试的话因 为$_SERVER['REMOTE_ADDR']和$_SERVER['REMOTE_ADDR']可能是127.0.0.1，所 以输出的内容为空。可以自己带入IP测试

 

或者 使用某网站的API

 

API 1.

 

1. 返回文字

 

http://api.hostip.info/get_html.php?ip=12.215.42.19&position=true

 

2. 返回图片

 

<IMG SRC="http://api.hostip.info/flag.php?ip=12.215.42.19" ALT="IP Address Lookup">

 

 

API 2. （需要申请api key ，免费的，类似google）

 

城市：

 

http://api.ipinfodb.com/v3/ip-city/?key=<your_api_key>&ip=74.125.45.100

 

国家（更快） ：

 

http://api.ipinfodb.com/v3/ip-country/?key=<your_api_key>&ip=74.125.45.100

 

 

Parameter Required Default Value

key	Yes	<empty>	API key provided with your free account.
ip	No	Client IP	IP address
format	No	raw	raw, xml, json
callback	No	<empty>	Required when using json callback.

Please use the appropriate API for your needs. You can help us keep the load low on our servers by making sure that :

• If you only need the country name, avoid using the city precision API.
• If you track your visitors, avoid querying our API for all your page views (you can store the geolocation in a cookie, see below for an example)

 

API Precision Timezone Domains lookups

ip-city	City	Yes	Yes
ip-country	Country	No	Yes

Please use the appropriate API for your needs. You can help us keep the load low on our servers by making sure that :

使用类：

 

<?php

    protected $errors = array();
    protected $service = 'api.ipinfodb.com';
    protected $version = 'v3';
    protected $apiKey = '';

    public function __construct(){}

    public function __destruct(){}

    public function setKey($key){
        if(!emptyempty($key)) $this->apiKey = $key;
    }

    public function getError(){
        return implode("\n", $this->errors);
    }

    public function getCountry($host){
        return $this->getResult($host, 'ip-country');
    }

    public function getCity($host){
        return $this->getResult($host, 'ip-city');
    }

    private function getResult($host, $name){
        $ip = @gethostbyname($host);

        if(preg_match('/^(?:25[0-5]|2[0-4]\d|1\d\d|[1-9]\d|\d)(?:[.](?:25[0-5]|2[0-4]\d|1\d\d|[1-9]\d|\d)){3}$/', $ip)){
            $xml = @file_get_contents('http://' . $this->service . '/' . $this->version . '/' . $name . '/?key=' . $this->apiKey . '&ip=' . $ip . '&format=xml');

            try{
                $response = @new SimpleXMLElement($xml);

                foreach($response as $field=>$value){
                    $result[(string)$field] = (string)$value;
                }

                return $result;
            }
            catch(Exception $e){
                $this->errors[] = $e->getMessage();
                return;
            }
        }

        $this->errors[] = '"' . $host . '" is not a valid IP address or hostname.';
        return;
    }
}
?>

 

<?
include('ip2locationlite.class.php');

//Load the class
$ipLite = new ip2location_lite;
$ipLite->setKey('<your_api_key>');

//Get errors and locations
$locations = $ipLite->getCity($_SERVER['REMOTE_ADDR']);
$errors = $ipLite->getError();

//Getting the result
echo "<p>\n";
echo "<strong>First result</strong><br />\n";
if (!emptyempty($locations) && is_array($locations)) {
  foreach ($locations as $field => $val) {
    echo $field . ' : ' . $val . "<br />\n";
  }
}
echo "</p>\n";

//Show errors
echo "<p>\n";
echo "<strong>Dump of all errors</strong><br />\n";
if (!emptyempty($errors) && is_array($errors)) {
  foreach ($errors as $error) {
    echo var_dump($error) . "<br /><br />\n";
  }
} else {
  echo "No errors" . "<br />\n";
}
echo "</p>\n";
