Dynamically displaying a visitor’s local currency based on their location significantly enhances the user experience, especially for e-commerce and SaaS platforms.

This tutorial demonstrates how to retrieve and display a visitor’s country currency from their IP address using PHP and the IP2Location BIN database. This method uses a local .bin file, which allows for ultra-fast, offline lookups without relying on third-party API calls.

Prerequisites & Setup #

Step 1: Download the IP2Location BIN Database #

  1. Download the free IP2Location LITE database (or the commercial version) from the IP2Location LITE Download Page.
  2. Unzip the downloaded file and copy the binary file into your project’s root directory.

Step 2: Download the IP2Location PHP Module #

  1. Download the official IP2Location PHP Module.
  2. If downloading manually, extract the package and copy the IP2Location.php file into your project’s root directory.

Step 3: Implementation #

Create a new file in the same folder and add the following sample code:

🐘
PHP 
<?php
    // Preset PHP settings
    error_reporting(E_ALL);
    ini_set('display_errors', 1);
    set_time_limit(0);
 
    require_once('IP2Location.php');
 
    // Standard lookup with no cache
    $loc = new IP2LocationDatabase('./databases/IP2LOCATION-LITE-DB1.BIN', IP2LocationDatabase::FILE_IO);
 
    $ip = $_SERVER['REMOTE_ADDR'];
 
    //lookup for country code
    $country_code = $loc->lookup($ip, IP2LocationDatabase::COUNTRY_CODE);
 
    //Lookup and display country code and country name
    echo "Country Code: " . $loc->lookup($ip, IP2LocationDatabase::COUNTRY_CODE) . "<br />";
    echo "Country Name: " . $loc->lookup($ip, IP2LocationDatabase::COUNTRY_NAME) . "<br />";
 
    //Displaying currency code based on country code retrieved.
    //If no record of currency code or no country code is found, default will be used.
    switch($country_code)
    {
        case 'CA':
            $currency_code = "CAD";
            echo "Country Currency: $currency_code 100";
            break;
        case 'MY':
            $currency_code = "MYR";
            echo "Country Currency: $currency_code 100";
            break;
        case 'JP':
            $currency_code = "JPY";
            echo "Country Currency: $currency_code 100";
            break;
        case 'US':
            $currency_code = "USD";
            echo "Country Currency: $currency_code 100";
            break;
        default:
            echo "Unable to translate IP to country. <br />";
            echo "$100.00";
            break;
    }
?>
