This library will allow you to get better insights into the world.

As a developer and a multilingual speaker I've always felt that localization was put on last priority since it was so time-consuming and error-prone.

Getting statistics for each country is a painful process that requires understanding the different ISO standards, and even then you're still left to piece the puzzle together yourself.

Luckily, GeoNames have been collecting statistical data about the world for the past few decades and offers that data via their API.

The aim of this library is to provide a single source of truth for country (ISO-3166), language (ISO-639-1), and other locale related statistical data, so that other developers can write better software which is up-to-date with the latest changes in the world.


If you're using Composer to manage dependencies:

composer require aternus/geonames-client

Then, after running composer update, you can load the class using Composer's autoloading:

require 'vendor/autoload.php';

Otherwise, you can simply require the file directly:

require_once 'vendor/aternus/geonames-client/src/Client.php';

And in either case, I'd suggest using an alias.

use GeoNames\Client as GeoNamesClient;

Other Useful Libraries

Please make sure to implement some kind of cache mechanism in order to save yourself time, bandwidth and be respectful to GeoNames for providing all that data for free.

If you're making heavy use of the statistical data, you can subscribe to their Premium Data plan.
