试试这个简单的PHP函数。

$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");
$continents = array(
"AF" => "Africa",
"AN" => "Antarctica",
"AS" => "Asia",
"EU" => "Europe",
"OC" => "Australia (Oceania)",
"NA" => "North America",
"SA" => "South America"
);
if (filter_var($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":

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 &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 )

从code.google中查看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

);


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


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

输出

有一个维护良好的ip->国家数据库的平面文件版本，由Perl社区在CPAN维护

有很多不同的方法……

解决方案1:

你可以使用的第三方服务是http://ipinfodb.com。它们提供主机名、地理位置和其他信息。

在这里注册API密钥:http://ipinfodb.com/register.php。这将允许您从他们的服务器检索结果，没有这个，它将无法工作。

复制并跳过下面的PHP代码:

$ipaddress = $_SERVER['REMOTE_ADDR'];
$api_key = 'YOUR_API_KEY_HERE';


$data = file_get_contents("http://api.ipinfodb.com/v3/ip-city/?key=$api_key&ip=$ipaddress&format=json");
$data = json_decode($data);
$country = $data['Country'];

缺点:

引用他们网站上的话:

我们的免费API是使用IP2Location Lite版本，提供更低准确性。

解决方案2:

此函数将使用http://www.netip.de/服务返回国家名称。

$ipaddress = $_SERVER['REMOTE_ADDR'];
function geoCheckIP($ip)
{
$response=@file_get_contents('http://www.netip.de/search?query='.$ip);


$patterns=array();
$patterns["country"] = '#Country: (.*?)&nbsp;#i';


$ipInfo=array();


foreach ($patterns as $key => $pattern)
{
$ipInfo[$key] = preg_match($pattern,$response,$value) && !empty($value[1]) ? $value[1] : 'not found';
}


return $ipInfo;
}


print_r(geoCheckIP($ipaddress));

输出:

Array ( [country] => DE - Germany )  // Full Country Name

尝试这个简单的一行代码，您将从他们的ip远程地址获得访客的国家和城市。

$tags = get_meta_tags('http://www.geobytes.com/IpLocator.htm?GetLocation&template=php3.txt&IpAddress=' . $_SERVER['REMOTE_ADDR']);
echo $tags['country'];
echo $tags['city'];

小开

我们可以使用geobytes.com来获得使用用户IP地址的位置

$user_ip = getIP();
$meta_tags = get_meta_tags('http://www.geobytes.com/IPLocator.htm?GetLocation&template=php3.txt&IPAddress=' . $user_ip);
echo '<pre>';
print_r($meta_tags);

它将返回这样的数据

Array(
[known] => true
[locationcode] => USCALANG
[fips104] => US
[iso2] => US
[iso3] => USA
[ison] => 840
[internet] => US

[latitude] => 34.0452
[longitude] => -118.2840
[timezone] => -08:00
[certainty] => 53
[mapbytesremaining] => Free
)

函数获取用户IP

function getIP(){
if (isset($_SERVER["HTTP_X_FORWARDED_FOR"])){
$pattern = "/^(([1-9]?[0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5]).){3}([1-9]?[0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$/";
if(preg_match($pattern, $_SERVER["HTTP_X_FORWARDED_FOR"])){
$userIP = $_SERVER["HTTP_X_FORWARDED_FOR"];
}else{
$userIP = $_SERVER["REMOTE_ADDR"];
}
}
else{
$userIP = $_SERVER["REMOTE_ADDR"];
}
return $userIP;

我正在使用ipinfodb.com api和得到你正在寻找的东西。

它是完全免费的，你只需要注册他们获得你的api密钥。你可以包括他们的php类从他们的网站下载，或者你可以使用url格式检索信息。

以下是我正在做的:

我在我的脚本中包含了他们的php类，并使用下面的代码:

$ipLite = new ip2location_lite;
$ipLite->setKey('your_api_key');
if(!$_COOKIE["visitorCity"]){ //I am using cookie to store information
$visitorCity = $ipLite->getCity($_SERVER['REMOTE_ADDR']);
if ($visitorCity['statusCode'] == 'OK') {
$data = base64_encode(serialize($visitorCity));
setcookie("visitorCity", $data, time()+3600*24*7); //set cookie for 1 week
}
}
$visitorCity = unserialize(base64_decode($_COOKIE["visitorCity"]));
echo $visitorCity['countryName'].' Region'.$visitorCity['regionName'];

这只是一张安全提示关于get_client_ip()的功能，这里的大部分答案都包含在get_geo_info_for_this_ip()的主函数中。

不要过分依赖请求头中的IP数据，如Client-IP或X-Forwarded-For，因为它们很容易被欺骗，但是你应该依赖于服务器和客户端$_SERVER['REMOTE_ADDR']之间实际建立的TCP连接的源IP作为它不能被欺骗

$_SERVER['HTTP_CLIENT_IP'] // can be spoofed
$_SERVER['HTTP_X_FORWARDED_FOR'] // can be spoofed
$_SERVER['REMOTE_ADDR']// can't be spoofed

获取被欺骗IP的国家是可以的，但请记住，在任何安全模型中使用这个IP(例如:禁止发送频繁请求的IP)都会破坏整个安全模型。恕我直言，我更喜欢使用实际的客户端IP，即使它是代理服务器的IP。

用这个你可以调用的类来回答“op”问题

$country = (new \Geo())->get('country'); // United Kingdom

其他可用的属性是:

$geo = new \Geo('185.35.50.4');
var_dump($geo->get('*')); // allias all / location
var_dump($geo->get('country'));
var_dump($geo->get('countrycode'));
var_dump($geo->get('state')); // allias region
var_dump($geo->get('city'));
var_dump($geo->get('address'));
var_dump($geo->get('continent'));
var_dump($geo->get('continentcode'));
var_dump($geo->get('request'));
var_dump($geo->get('latitude'));
var_dump($geo->get('longitude'));
var_dump($geo->get('accuracy'));
var_dump($geo->get('timezonde'));
var_dump($geo->get('currencyCode'));
var_dump($geo->get('currencySymbol'));
var_dump($geo->get('currencySymbolUTF8'));

这可以接受吗? 纯PHP

以下是使用guzzle的更清晰的工作版本:

你可以使用curl而不是guzzle，这只是一个简单的get请求。

$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",
"AS" => "Asia",

如果你需要尽快获得国家，我会建议geoip插件为您的web服务器。

对于nginx 在这里;

在你正确设置后，你将从$_SERVER变量中获得国家代码。

仅用4行代码就实现了这一点!

$user_ip = '0.0.0.0';
$user_ip = $_SERVER['REMOTE_ADDR'];
$close_url = stream_context_create(array('http' => array('header'=>'Connection: close\r\n')));
$user_country = json_decode(file_get_contents("https://ipinfo.io/$user_ip/json",false,$close_url));
echo "Yes! we ship to your country: <b>" . $user_country->country . "</b>";

/ /输出是的!我们的船到你的国家我们

注意: $close_url用于在内容被检索后尽快结束file_get_contents，它提高了请求的速度x5。

如果你想显示完整的国家名称，你可以点击下面，看看如何。

您可以使用此代码片段。

 if($a = unserialize(file_get_contents('http://www.geoplugin.net/php.gp?ip='.$_SERVER['REMOTE_ADDR']))){
$countrycode= $a['geoplugin_countryCode'];
if ($countrycode=='UK' ){
header( 'Location: https://www.example.co.uk/' ) ;exit;
}
}
