使用以下服务

1) http://api.hostip.info/get_html.php?ip=12.215.42.19

2)

$json = file_get_contents('http://freegeoip.appspot.com/json/66.102.13.106');
$expression = json_decode($json);
print_r($expression);

3) http://ipinfodb.com/ip_location_api.php

在code.google上查看php-ip-2-country。他们提供的数据库每天都会更新，所以如果你拥有自己的SQL服务器，就没有必要连接到外部服务器进行检查。所以使用代码你只需要输入:

<?php
$ip = $_SERVER['REMOTE_ADDR'];

if(!empty($ip)){
        require('./phpip2country.class.php');

        /**
         * Newest data (SQL) avaliable on project website
         * @link http://code.google.com/p/php-ip-2-country/
         */
        $dbConfigArray = array(
                'host' => 'localhost', //example host name
                'port' => 3306, //3306 -default mysql port number
                'dbName' => 'ip_to_country', //example db name
                'dbUserName' => 'ip_to_country', //example user name
                'dbUserPassword' => 'QrDB9Y8CKMdLDH8Q', //example user password
                'tableName' => 'ip_to_country', //example table name
        );

        $phpIp2Country = new phpIp2Country($ip,$dbConfigArray);
        $country = $phpIp2Country->getInfo(IP_COUNTRY_NAME);
        echo $country;
?>

示例代码(来自资源)

<?
require('phpip2country.class.php');

$dbConfigArray = array(
        'host' => 'localhost', //example host name
        'port' => 3306, //3306 -default mysql port number
        'dbName' => 'ip_to_country', //example db name
        'dbUserName' => 'ip_to_country', //example user name
        'dbUserPassword' => 'QrDB9Y8CKMdLDH8Q', //example user password
        'tableName' => 'ip_to_country', //example table name
);

$phpIp2Country = new phpIp2Country('213.180.138.148',$dbConfigArray);

print_r($phpIp2Country->getInfo(IP_INFO));
?>

输出

Array
(
    [IP_FROM] => 3585376256
    [IP_TO] => 3585384447
    [REGISTRY] => RIPE
    [ASSIGNED] => 948758400
    [CTRY] => PL
    [CNTRY] => POL
    [COUNTRY] => POLAND
    [IP_STR] => 213.180.138.148
    [IP_VALUE] => 3585378964
    [IP_FROM_STR] => 127.255.255.255
    [IP_TO_STR] => 127.255.255.255
)

试试这个简单的PHP函数。

<?php

function ip_info($ip = NULL, $purpose = "location", $deep_detect = TRUE) {
    $output = NULL;
    if (filter_var($ip, FILTER_VALIDATE_IP) === FALSE) {
        $ip = $_SERVER["REMOTE_ADDR"];
        if ($deep_detect) {
            if (filter_var(@$_SERVER['HTTP_X_FORWARDED_FOR'], FILTER_VALIDATE_IP))
                $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
            if (filter_var(@$_SERVER['HTTP_CLIENT_IP'], FILTER_VALIDATE_IP))
                $ip = $_SERVER['HTTP_CLIENT_IP'];
        }
    }
    $purpose    = str_replace(array("name", "\n", "\t", " ", "-", "_"), NULL, strtolower(trim($purpose)));
    $support    = array("country", "countrycode", "state", "region", "city", "location", "address");
    $continents = array(
        "AF" => "Africa",
        "AN" => "Antarctica",

        "NA" => "North America",
        "SA" => "South America"
    );
    if (filter_var($ip, FILTER_VALIDATE_IP) && in_array($purpose, $support)) {
        $ipdat = @json_decode(file_get_contents("http://www.geoplugin.net/json.gp?ip=" . $ip));
        if (@strlen(trim($ipdat->geoplugin_countryCode)) == 2) {
            switch ($purpose) {
                case "location":
                    $output = array(
                        "city"           => @$ipdat->geoplugin_city,
                        "state"          => @$ipdat->geoplugin_regionName,

                        "country_code"   => @$ipdat->geoplugin_countryCode,
                        "continent"      => @$continents[strtoupper($ipdat->geoplugin_continentCode)],
                        "continent_code" => @$ipdat->geoplugin_continentCode
                    );
                    break;
                case "address":
                    $address = array($ipdat->geoplugin_countryName);
                    if (@strlen($ipdat->geoplugin_regionName) >= 1)
                        $address[] = $ipdat->geoplugin_regionName;
                    if (@strlen($ipdat->geoplugin_city) >= 1)
                        $address[] = $ipdat->geoplugin_city;
                    $output = implode(", ", array_reverse($address));
                    break;
                case "city":
                    $output = @$ipdat->geoplugin_city;
                    break;
                case "state":
                    $output = @$ipdat->geoplugin_regionName;
                    break;
                case "region":
                    $output = @$ipdat->geoplugin_regionName;
                    break;
                case "country":
                    $output = @$ipdat->geoplugin_countryName;
                    break;
                case "countrycode":
                    $output = @$ipdat->geoplugin_countryCode;
                    break;
            }
        }
    }
    return $output;
}

?>

使用方法:

Example1:获取访问者IP地址的详细信息

<?php

echo ip_info("Visitor", "Country"); // India
echo ip_info("Visitor", "Country Code"); // IN
echo ip_info("Visitor", "State"); // Andhra Pradesh
echo ip_info("Visitor", "City"); // Proddatur
echo ip_info("Visitor", "Address"); // Proddatur, Andhra Pradesh, India

print_r(ip_info("Visitor", "Location")); // Array ( [city] => Proddatur [state] => Andhra Pradesh [country] => India [country_code] => IN [continent] => Asia [continent_code] => AS )

?>

例2:获取任意IP地址的详细信息。[支持IPV4和IPV6]

<?php

echo ip_info("173.252.110.27", "Country"); // United States
echo ip_info("173.252.110.27", "Country Code"); // US
echo ip_info("173.252.110.27", "State"); // California
echo ip_info("173.252.110.27", "City"); // Menlo Park
echo ip_info("173.252.110.27", "Address"); // Menlo Park, California, United States

print_r(ip_info("173.252.110.27", "Location")); // Array ( [city] => Menlo Park [state] => California [country] => United States [country_code] => US [continent] => North America [continent_code] => NA )

?>

您可以使用http://www.geoplugin.net/上的简单API

$xml = simplexml_load_file("http://www.geoplugin.net/xml.gp?ip=".getRealIpAddr());
echo $xml->geoplugin_countryName ;


echo "<pre>";
foreach ($xml as $key => $value)
{
    echo $key , "= " , $value ,  " \n" ;
}
echo "</pre>";

函数使用

function getRealIpAddr()
{
    if (!empty($_SERVER['HTTP_CLIENT_IP']))   //check ip from share internet
    {
      $ip=$_SERVER['HTTP_CLIENT_IP'];
    }
    elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))   //to check ip is pass from proxy
    {
      $ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
    }
    else
    {
      $ip=$_SERVER['REMOTE_ADDR'];
    }
    return $ip;
}

输出

United States
geoplugin_city= San Antonio
geoplugin_region= TX
geoplugin_areaCode= 210
geoplugin_dmaCode= 641
geoplugin_countryCode= US
geoplugin_countryName= United States
geoplugin_continentCode= NA
geoplugin_latitude= 29.488899230957
geoplugin_longitude= -98.398696899414
geoplugin_regionCode= TX
geoplugin_regionName= Texas
geoplugin_currencyCode= USD
geoplugin_currencySymbol= $
geoplugin_currencyConverter= 1

它让你有很多选择可以选择

谢谢

这可以接受吗? 纯PHP

$country = geoip_country_code_by_name($_SERVER['REMOTE_ADDR']);
print $country;

裁判:https://www.php.net/manual/en/function.geoip-country-code-by-name.php

由CPAN的Perl社区维护的ip->国家数据库有一个维护良好的平面文件版本

访问这些文件不需要数据服务器，数据本身大约是515k

Higemaru编写了一个PHP包装器来处理这些数据:PHP -ip-country-fast
