Script PHP Untuk Redirect Visitor Berdasarkan Negara

Skrip PHP Untuk Mengetahui Negara Pengunjung berdasarkan IP address sudah pernah dibahas pada artikel sebelumnya disini. Sekarang sedot code ingin membagikan bagaimana cara redirect pengunjung berdasarkan negara menggunakan curl freegeoip.net.

Tutorial ini sebenarnya bisa juga untuk memblok visitor dari negara-negara tertentu. Jika anda adalah seorang internet marketer mungkin akan sering membutuhkan script bagaimana cara meredirect atau memblok visitor ini.

Mendapatkan IP, Validasi IP, dan GeoIP

Berikut adalah scriptnya:

<?php
function getGeoIP($ip = null, $jsonArray = false) {
    try {
        // If no IP is provided use the current users IP
        if($ip == null) {
            $ip   = filter_input(INPUT_SERVER, 'REMOTE_ADDR');
        }
        // If the IP is equal to 127.0.0.1 (IPv4) or ::1 (IPv6) then cancel, won't work on localhost
        if($ip == "127.0.0.1" || $ip == "::1") {
            throw new Exception('You are on a local sever, this script won\'t work right.');
        }
        // Make sure IP provided is valid
        if(!filter_var($ip, FILTER_VALIDATE_IP)) {
            throw new Exception('Invalid IP address "' . $ip . '".');
        }
        if(!is_bool($jsonArray)) {
            throw new Exception('The second parameter must be a boolean - true (return array) or false (return JSON object); default is false.');
        }
        // Fetch JSON data with the IP provided
        $url  = "http://freegeoip.net/json/" . $ip;
        // Return the contents, supress errors because we will check in a bit
        $json = @file_get_contents($url);
        // Did we manage to get data?
        if($json === false) {
            return false;
        }
        // Decode JSON
        $json = json_decode($json, $jsonArray);
        // If an error happens we can assume the JSON is bad or invalid IP
        if($json === null) {
            // Return false
            return false;
        } else {
            // Otherwise return JSON data
            return $json;
        }
    } catch(Exception $e) {
        return $e->getMessage();
    }
}
function get_ip_address() {
    $ip_keys = array('HTTP_CLIENT_IP', 'HTTP_X_FORWARDED_FOR', 'HTTP_X_FORWARDED', 'HTTP_X_CLUSTER_CLIENT_IP', 'HTTP_FORWARDED_FOR', 'HTTP_FORWARDED', 'REMOTE_ADDR');
    foreach ($ip_keys as $key) {
        if (array_key_exists($key, $_SERVER) === true) {
            foreach (explode(',', $_SERVER[$key]) as $ip) {
                // trim for safety measures
                $ip = trim($ip);
                // attempt to validate IP
                if (validate_ip($ip)) {
                    return $ip;
                }
            }
        }
    }

    return isset($_SERVER['REMOTE_ADDR']) ? $_SERVER['REMOTE_ADDR'] : false;
}
function validate_ip($ip)
{
    if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_IPV4 | FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE) === false) {
        return false;
    }
    return true;
}

Terlihat ada beberapa fungsi, setidaknya ada 3 fungsi(). mendapatkan ip address, validasi ip, dan menentukan lokasi negaranya. Sekarang tinggal kita eksekusi seperti ini.

//https://sedotcode.blogspot.com/2017/09/redirect-visitor-by-country.html
$ip = get_ip_address();
$userGeoData = getGeoIP($ip); 

echo "IP: " .$ip."<br>";

echo "Kode Negara: " .$userGeoData->country_code."<br>";

echo "Nama Negara: " .$userGeoData->country_name."<br>";

echo "Kota: " .$userGeoData->city."<br>";

PHP Redirect By Country 

// Tutorial => https://sedotcode.blogspot.com/2017/09/redirect-visitor-by-country.html
// Code Negara (2 Digit) indonesia = ID => https://countrycode.org/
$userGeoData = getGeoIP(get_ip_address()); 

// echo "Kode Negara: " .$userGeoData->country_code."<br>";

// echo "Nama Negara: " .$userGeoData->country_name."<br>";

$kode_negara = $userGeoData->country_code;

if ($kode_negara == 'ID' || $kode_negara == "dan seterusnya" ) {
    header("HTTP/1.1 301 Moved Permanently");
    header("Location: //fb.com"); 
}

Penjelasan:
Setelah mendapatkan nama negara berdasarkan ip, maka kita bisa redirect ke halaman tertentu. Seperti pada contoh diatas. Jika pengunjung berasal dari Indonesia maka akan di arahkan ke facebook.com.
