+
+[![Build Status](https://travis-ci.org/matriphe/php-iso-639.svg)](https://travis-ci.org/matriphe/php-iso-639)
+
+PHP library to convert ISO-639-1 code to language name, based on Wikipedia's [List of ISO 639-1 codes](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes).
+
+## Installation
+
+Using composer: `composer require matriphe/iso-639`
+
+## Usage Example
+
+```php
+<?php
+
+required 'src/ISO639.php';
+//required 'vendor/autoload.php'; // If using composer
+
+$iso = new Matriphe\ISO639\ISO639;
+
+// Get language name from ISO-639-1 code
+echo $iso->languageByCode1('en'); // English
+echo $iso->languageByCode1('id'); // Indonesian
+echo $iso->languageByCode1('jv'); // Javanese
+
+// Get native language name from ISO-639-1 code
+echo $iso->nativeByCode1('en'); // English
+echo $iso->nativeByCode1('id'); // Bahasa Indonesia
+echo $iso->nativeByCode1('jv'); // basa Jawa
+
+// Get language name from ISO-639-2t code
+echo $iso->languageByCode2t('eng'); // English
+echo $iso->languageByCode2t('ind'); // Indonesian
