從他們的 IP 獲取訪問者所在的國家/地區

[英]Getting visitors country from their IP

我想通過他們的 IP 獲得訪問者的國家......現在我正在使用這個( http://api.hostip.info/country.php? ip=......)

這是我的代碼:

<?php

if (isset($_SERVER['HTTP_CLIENT_IP']))
{
    $real_ip_adress = $_SERVER['HTTP_CLIENT_IP'];
}

if (isset($_SERVER['HTTP_X_FORWARDED_FOR']))
{
    $real_ip_adress = $_SERVER['HTTP_X_FORWARDED_FOR'];
}
else
{
    $real_ip_adress = $_SERVER['REMOTE_ADDR'];
}

$cip = $real_ip_adress;
$iptolocation = 'http://api.hostip.info/country.php?ip=' . $cip;
$creatorlocation = file_get_contents($iptolocation);

?>

好吧,它工作正常,但問題是,它返回的是國家代碼,如 US 或 CA.,而不是整個國家名稱,如美國或加拿大。

那么,除了 hostip.info 提供這個之外,還有什么好的選擇嗎?

我知道我可以編寫一些代碼,最終將這兩個字母變成整個國家/地區名稱,但是我懶得編寫包含所有國家/地區的代碼...

PS:出於某種原因,我不想使用任何現成的 CSV 文件或任何可以為我獲取此信息的代碼,例如 ip2country 現成的代碼和 CSV。

試試這個簡單的 PHP 函數。

<?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(

        "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));

                    );
                    break;

                        $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 "region":
                    $output = @$ipdat->geoplugin_regionName;
                    break;
                case "country":

                    break;
            }
        }
    }
    return $output;
}

?>

如何使用:

示例 1:獲取訪問者 IP 地址詳細信息

<?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 )

?>

示例 2:獲取任何 IP 地址的詳細信息。 【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 )

?>

您可以使用來自http://www.geoplugin.net/的簡單 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>";

使用的功能

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;
}

輸出

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

它讓你有很多可以玩的選擇

謝謝

我嘗試了 Chandra 的回答,但我的服務器配置不允許file_get_contents()

PHP Warning: file_get_contents() URL file-access is disabled in the server configuration

我修改了 Chandra 的代碼,使其也適用於使用 cURL 的服務器:

function ip_visitor_country()
{

    $client  = @$_SERVER['HTTP_CLIENT_IP'];
    $forward = @$_SERVER['HTTP_X_FORWARDED_FOR'];
    $remote  = $_SERVER['REMOTE_ADDR'];
    $country  = "Unknown";

    if(filter_var($client, FILTER_VALIDATE_IP))
    {
        $ip = $client;
    }
    elseif(filter_var($forward, FILTER_VALIDATE_IP))
    {
        $ip = $forward;
    }
    else
    {
        $ip = $remote;
    }
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, "http://www.geoplugin.net/json.gp?ip=".$ip);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    $ip_data_in = curl_exec($ch); // string
    curl_close($ch);

    $ip_data = json_decode($ip_data_in,true);
    $ip_data = str_replace('&quot;', '"', $ip_data); // for PHP 5.2 see stackoverflow.com/questions/3110487/

    if($ip_data && $ip_data['geoplugin_countryName'] != null) {
        $country = $ip_data['geoplugin_countryName'];
    }

    return 'IP: '.$ip.' # Country: '.$country;
}

echo ip_visitor_country(); // output Coutry name

?>

希望有幫助;-)

使用 MaxMind GeoIP(如果您還沒有准備好付款,則使用 GeoIPLite)。

$gi = geoip_open('GeoIP.dat', GEOIP_MEMORY_CACHE);
$country = geoip_country_code_by_addr($gi, $_SERVER['REMOTE_ADDR']);
geoip_close($gi);

您可以使用來自http://ip-api.com的網絡服務
在您的 php 代碼中,執行以下操作:

<?php
$ip = $_REQUEST['REMOTE_ADDR']; // the IP address to query
$query = @unserialize(file_get_contents('http://ip-api.com/php/'.$ip));
if($query && $query['status'] == 'success') {
  echo 'Hello visitor from '.$query['country'].', '.$query['city'].'!';
} else {
  echo 'Unable to get location';
}
?>

查詢還有許多其他信息:

array (
  'status'      => 'success',
  'country'     => 'COUNTRY',
  'countryCode' => 'COUNTRY CODE',
  'region'      => 'REGION CODE',
  'regionName'  => 'REGION NAME',
  'city'        => 'CITY',
  'zip'         => ZIP CODE,
  'lat'         => LATITUDE,
  'lon'         => LONGITUDE,
  'timezone'    => 'TIME ZONE',
  'isp'         => 'ISP NAME',
  'org'         => 'ORGANIZATION NAME',
  'as'          => 'AS NUMBER / NAME',
  'query'       => 'IP ADDRESS USED FOR QUERY',
)

實際上,您可以調用http://api.hostip.info/?ip=123.125.114.144來獲取以 XML 形式呈現的信息。

從 code.google 查看php-ip-2-country 他們提供的數據庫每天都會更新,因此如果您托管自己的 SQL 服務器,則無需連接到外部服務器來檢查。 因此,使用代碼您只需鍵入:

<?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;
?>

示例代碼(來自資源)

<?
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));
?>

輸出

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
)

使用以下服務

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

我們可以使用 geobytes.com 使用用戶 IP 地址獲取位置

$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);

它會像這樣返回數據

Array(
    [known] => true
    [locationcode] => USCALANG
    [fips104] => US
    [iso2] => US
    [iso3] => USA
    [ison] => 840
    [internet] => US
    [countryid] => 254
    [country] => United States
    [regionid] => 126
    [region] => California
    [regioncode] => CA
    [adm1code] =>     
    [cityid] => 7275
    [city] => Los Angeles
    [latitude] => 34.0452
    [longitude] => -118.2840
    [timezone] => -08:00
    [certainty] => 53
    [mapbytesremaining] => Free
)

獲取用戶IP的函數

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;
}

試試這個簡單的一行代碼,您將從他們的 ip 遠程地址獲取訪問者的國家和城市。

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

有一個維護良好的平面文件版本的 ip->country 數據庫,由CPAN的 Perl 社區維護

訪問這些文件不需要數據服務器,數據本身大約為 515k

Higemaru 編寫了一個 PHP 包裝器來處理該數據: php-ip-country-fast

許多不同的方法來做到這一點...

解決方案#1:

您可以使用的一項第三方服務是http://ipinfodb.com 它們提供主機名、地理位置和其他信息。

在此處注冊 API 密鑰:http: //ipinfodb.com/register.php 這將允許您從他們的服務器檢索結果,否則它將無法工作。

復制並粘貼以下 PHP 代碼:

$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'];

缺點:

引用他們的網站:

我們的免費 API 使用的是 IP2Location Lite 版本,它提供了較低的准確性。

解決方案#2:

此函數將使用http://www.netip.de/服務返回國家名稱。

$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));

輸出:

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

我的服務ipdata.co提供 5 種語言的國家名稱! 以及來自任何 IPv4 或 IPv6 地址的組織、貨幣、時區、呼叫代碼、標志、移動運營商數據、代理數據和 Tor 出口節點狀態數據。

此答案使用非常有限的“測試”API 密鑰,僅用於測試幾個調用。 注冊您自己的免費 API 密鑰並每天收到多達 1500 個開發請求。

它還具有極強的可擴展性,全球 10 個區域,每個區域每秒能夠處理超過 10,000 個請求!

選項包括; 英語 (en)、德語 (de)、日語 (ja)、法語 (fr) 和簡體中文 (za-CH)

$ip = '74.125.230.195';
$details = json_decode(file_get_contents("https://api.ipdata.co/{$ip}?api-key=test"));
echo $details->country_name;
//United States
echo $details->city;
//Mountain View
$details = json_decode(file_get_contents("https://api.ipdata.co/{$ip}?api-key=test/zh-CN"));
echo $details->country_name;
//美國

不確定這是否是一項新服務,但現在(2016 年)php 中最簡單的方法是使用 geoplugin 的 php 網絡服務: http ://www.geoplugin.net/php.gp:

基本用法:

// GET IP ADDRESS
if (!empty($_SERVER['HTTP_CLIENT_IP'])) {
    $ip = $_SERVER['HTTP_CLIENT_IP'];
} else if (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
    $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
} else if (!empty($_SERVER['REMOTE_ADDR'])) {
    $ip = $_SERVER['REMOTE_ADDR'];
} else {
    $ip = false;
}

// CALL THE WEBSERVICE
$ip_info = unserialize(file_get_contents('http://www.geoplugin.net/php.gp?ip='.$ip));

他們還提供了一個現成的類: http ://www.geoplugin.com/_media/webservices/geoplugin.class.php.tgz?id=webservices%3Aphp&cache=cache

那可以接受嗎? 純PHP

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

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

您可以使用http://ipinfo.io/獲取 ip 地址的詳細信息。它易於使用。

<?php
    function ip_details($ip)
    {
    $json = file_get_contents("http://ipinfo.io/{$ip}");
    $details = json_decode($json);
    return $details;
    }

    $details = ip_details(YoUR IP ADDRESS); 

    echo $details->city;
    echo "<br>".$details->country; 
    echo "<br>".$details->org; 
    echo "<br>".$details->hostname; /

    ?>

具有IP 地址到國家/地區 API 的單班輪

echo file_get_contents('https://ipapi.co/8.8.8.8/country_name/');

> United States

例子 :

https://ipapi.co/country_name/ - 你的國家

https://ipapi.co/8.8.8.8/country_name/ - IP 8.8.8.8 的國家

我正在使用ipinfodb.com api 並得到你正在尋找的東西。

它完全免費,您只需向他們注冊即可獲取您的 api 密鑰。 您可以通過從他們的網站下載來包含他們的 php 類,或者您可以使用 url 格式來檢索信息。

這就是我正在做的事情:

我將他們的 php 類包含在我的腳本中並使用以下代碼:

$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'];

而已。

127.0.0.1替換為訪問者 IpAddress。

$country = geoip_country_name_by_name('127.0.0.1');

安裝說明在這里閱讀此內容以了解如何獲取城市、州、國家、經度、緯度等...

我有一個簡短的答案,我在一個項目中使用過。 在我的回答中,我認為您有訪客 IP 地址。

$ip = "202.142.178.220";
$ipdat = @json_decode(file_get_contents("http://www.geoplugin.net/json.gp?ip=" . $ip));
//get ISO2 country code
if(property_exists($ipdat, 'geoplugin_countryCode')) {
    echo $ipdat->geoplugin_countryCode;
}
//get country full name
if(property_exists($ipdat, 'geoplugin_countryName')) {
    echo $ipdat->geoplugin_countryName;
}

我知道這很舊,但我在這里嘗試了其他一些解決方案,它們似乎已經過時或者只是返回 null。 所以我就是這樣做的。

使用http://www.geoplugin.net/json.gp?ip=不需要任何類型的注冊或支付服務費用。

function get_client_ip_server() {
  $ipaddress = '';
if (isset($_SERVER['HTTP_CLIENT_IP']))
  $ipaddress = $_SERVER['HTTP_CLIENT_IP'];
else if(isset($_SERVER['HTTP_X_FORWARDED_FOR']))
  $ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];
else if(isset($_SERVER['HTTP_X_FORWARDED']))
  $ipaddress = $_SERVER['HTTP_X_FORWARDED'];
else if(isset($_SERVER['HTTP_FORWARDED_FOR']))
  $ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
else if(isset($_SERVER['HTTP_FORWARDED']))
  $ipaddress = $_SERVER['HTTP_FORWARDED'];
else if(isset($_SERVER['REMOTE_ADDR']))
  $ipaddress = $_SERVER['REMOTE_ADDR'];
else
  $ipaddress = 'UNKNOWN';

  return $ipaddress;
}

$ipaddress = get_client_ip_server();

function getCountry($ip){
    $curlSession = curl_init();
    curl_setopt($curlSession, CURLOPT_URL, 'http://www.geoplugin.net/json.gp?ip='.$ip);

我寫了一個基於“Chandra Nakka”答案的課程。 希望它可以幫助人們將地理插件中的信息保存到會話中,以便在調用信息時加載速度更快。 它還將值保存到私有數組中,因此在同一代碼中調用是最快的。

用這門課回答'op'問題,你可以打電話

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

其他可用的屬性是:

$geo = new \Geo('185.35.50.4');
var_dump($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'));

返回

您可以使用此代碼片段。

 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;
        }
    }

User Country API正是您所需要的。 這是一個使用 file_get_contents() 的示例代碼,就像您最初所做的那樣:

$result = json_decode(file_get_contents('http://usercountry.com/v1.0/json/'.$cip), true);
$result['country']['name']; // this contains what you need

您可以使用 ipstack geo API 獲取訪問者國家和城市。您需要獲取自己的 ipstack API,然后使用以下代碼:

<?php
 $ip = $_SERVER['REMOTE_ADDR']; 
 $api_key = "YOUR_API_KEY";
 $freegeoipjson = file_get_contents("http://api.ipstack.com/".$ip."?access_key=".$api_key."");
 $jsondata = json_decode($freegeoipjson);
 $countryfromip = $jsondata->country_name;
 echo "Country: ". $countryfromip ."";
?>

這只是關於get_client_ip()功能的安全說明,這里的大多數答案都包含在get_geo_info_for_this_ip()的主要功能中。

不要過分依賴Client-IPX-Forwarded-For等請求標頭中的 IP 數據,因為它們很容易被欺騙,但是您應該依賴於我們之間實際建立的 TCP 連接的源 IP服務器和客戶端$_SERVER['REMOTE_ADDR']因為它不能被欺騙

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

獲取欺騙 IP 的國家/地區是可以的,但請記住,在任何安全模型中使用此 IP(例如:禁止發送頻繁請求的 IP)都會破壞整個安全模型。 恕我直言,我更喜歡使用實際的客戶端 IP,即使它是代理服務器的 IP。

嘗試

  <?php
  //gives you the IP address of the visitors
  if (!empty($_SERVER['HTTP_CLIENT_IP'])) {
      $ip = $_SERVER['HTTP_CLIENT_IP'];}
  else if (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
      $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];
  } else {
      $ip = $_SERVER['REMOTE_ADDR'];
  }

  //return the country code
  $url = "http://api.wipmania.com/$ip";
  $country = file_get_contents($url);
  echo $country;

  ?>

您可以使用我的服務: https ://SmartIP.io,它提供了任何 IP 地址的完整國家名稱和城市名稱。 我們還公開了時區、貨幣、代理檢測、TOR 節點檢測和加密檢測。

您只需要注冊並獲得一個免費的 API 密鑰,該密鑰每月允許 250,000 個請求。

使用官方 PHP 庫,API 調用變為:

$apiKey = "your API key";
$smartIp = new SmartIP($apiKey);
$response = $smartIp->requestIPData("8.8.8.8");

echo "\nstatus code: " . $response->{"status-code"};
echo "\ncountry name: " . $response->country->{"country-name"};

PHP代碼獲取國家、城市、
大陸等使用 IP 地址

    $ip = $_SERVER["REMOTE_ADDR"];
      
    // Use JSON encoded string and converts 
    // it into a PHP variable 
    $ipdat = @json_decode(file_get_contents( 
        "http://www.geoplugin.net/json.gp?ip=" . $ip)); 
       
    $country = $ipdat->geoplugin_countryName; 
    $city = $ipdat->geoplugin_city; 
    $continent_name = $ipdat->geoplugin_continentName; 
    $latitude = $ipdat->geoplugin_latitude; 
    $longitude = $ipdat->geoplugin_longitude; 
    $currency_symbol = $ipdat->geoplugin_currencySymbol; 
    $currency_code = $ipdat->geoplugin_currencyCode; 
    $timezone = $ipdat->geoplugin_timezone; 

我想通過他們的IP獲取訪問者國家/地區...現在我正在使用它( http://api.hostip.info/country.php?ip= ......)

這是我的代碼:

<?php

if (isset($_SERVER['HTTP_CLIENT_IP']))
{
    $real_ip_adress = $_SERVER['HTTP_CLIENT_IP'];
}

if (isset($_SERVER['HTTP_X_FORWARDED_FOR']))
{
    $real_ip_adress = $_SERVER['HTTP_X_FORWARDED_FOR'];
}
else
{
    $real_ip_adress = $_SERVER['REMOTE_ADDR'];
}

$cip = $real_ip_adress;
$iptolocation = 'http://api.hostip.info/country.php?ip=' . $cip;
$creatorlocation = file_get_contents($iptolocation);

?>

好吧,它工作正常,但事實是,這將返回國家代碼(例如美國或加拿大),而不是整個國家名稱(例如美國或加拿大)。

那么,有沒有好的替代hostip.info的方法呢?

我知道我可以編寫一些代碼,最終將這兩個字母轉換為整個國家/地區名稱,但是我懶得編寫包含所有國家/地區的代碼...

PS:出於某種原因,我不想使用任何現成的CSV文件或任何可以為我獲取此信息的代碼,例如ip2country現成的代碼和CSV。

這是使用 guzzle 接受的答案的更簡潔和有效的版本:

您可以使用 curl 而不是 guzzle 它只是一個簡單的獲取請求。

如果您需要盡快獲得國家/地區,我建議您的網絡服務器使用 geoip 插件。

對於這里的 nginx ;

正確設置后,您將從$_SERVER變量中獲取國家代碼。

我每秒執行大約 500(+-) 次,非常快。

只需 4 行代碼即可實現這一目標!

$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>";

//輸出是的! 我們運送到您的國家美國

注意: $close_url用於在獲取內容后盡快結束 file_get_contents,它提高了請求的速度 x5。

如果您想顯示完整的國家/地區名稱,您可以點擊下方查看如何操作。
