PHP NACE Codes

A PHP library for working with NACE (Nomenclature of Economic Activities) codes used by the European Union for classifying business activities.

Features

• Complete NACE Rev. 2 code database
• Hierarchical structure support (Sections, Divisions, Groups, Codes)
• Multi-language translations (25 languages included)
• Framework-agnostic translation system with adapters for:
  • Standalone PHP (zero dependencies)
  • Symfony
  • Laravel
• PHP 7.1 - 8.4 support

Installation

composer require xterr/php-nacecodes

Quick Start

Basic Usage (Without Translations)

use Xterr\NaceCodes\NaceCodesFactory;

$factory = new NaceCodesFactory();

// Get all NACE codes
$codes = $factory->getCodes();

// Find a specific code
$code = $codes->getByCodeAndVersion('6201', 2);
echo $code->getName(); // "Computer programming activities"
echo $code->getCode(); // "6201"

// Get sections, divisions, groups
$sections = $factory->getSections();
$section = $sections->getByCodeAndVersion('J', 2);
echo $section->getName(); // "INFORMATION AND COMMUNICATION"

$divisions = $factory->getDivisions();
$groups = $factory->getGroups();

With Translations (Standalone PHP)

The library includes a zero-dependency translator for standalone usage:

use Xterr\NaceCodes\NaceCodesFactory;
use Xterr\NaceCodes\Translation\Adapter\ArrayTranslator;

// Create translator with German locale
$translator = new ArrayTranslator(null, 'de');

$factory = new NaceCodesFactory(null, $translator);

$sections = $factory->getSections();
$section = $sections->getByCodeAndVersion('A', 2);

echo $section->getName();      // "AGRICULTURE, FORESTRY AND FISHING" (original)
echo $section->getLocalName(); // "LAND- UND FORSTWIRTSCHAFT, FISCHEREI" (translated)

// Change locale at runtime
$translator->setLocale('fr');

// Get available locales
$locales = $translator->getAvailableLocales();
// ['bg', 'cs', 'da', 'de', 'el', 'es', 'et', 'fi', 'fr', 'hr', 'hu', 'it', 'lt', 'lv', 'mt', 'nl', 'no', 'pl', 'pt', 'ro', 'ru', 'sk', 'sl', 'sv', 'tr']

With Symfony Translator

use Xterr\NaceCodes\NaceCodesFactory;
use Xterr\NaceCodes\Translation\Adapter\SymfonyTranslatorAdapter;
use Symfony\Component\Translation\Translator;

// Your existing Symfony translator
$symfonyTranslator = new Translator('de');
// ... configure loaders and resources

$adapter = new SymfonyTranslatorAdapter($symfonyTranslator);
$factory = new NaceCodesFactory(null, $adapter);

$code = $factory->getCodes()->getByCodeAndVersion('0111', 2);
echo $code->getLocalName(); // German translation

With Laravel Translator

use Xterr\NaceCodes\NaceCodesFactory;
use Xterr\NaceCodes\Translation\Adapter\LaravelTranslatorAdapter;

// In a Laravel application
$adapter = new LaravelTranslatorAdapter(app('translator'));
$factory = new NaceCodesFactory(null, $adapter);

$code = $factory->getCodes()->getByCodeAndVersion('0111', 2);
echo $code->getLocalName(); // Translated based on Laravel's locale

API Reference

NaceCodesFactory

$factory = new NaceCodesFactory(?string $baseDirectory = null, ?TranslatorInterface $translator = null);

$factory->getCodes();      // Returns NaceCodes
$factory->getSections();   // Returns NaceSections
$factory->getDivisions();  // Returns NaceDivisions
$factory->getGroups();     // Returns NaceGroups
$factory->getMappings();   // Returns NaceCodesMappings

Entity Methods

All entities (NaceCode, NaceSection, NaceDivision, NaceGroup) share these methods:

$entity->getCode();      // NACE code (e.g., "6201", "J", "62", "620")
$entity->getName();      // Original English name
$entity->getLocalName(); // Translated name (falls back to getName() if no translation)
$entity->getVersion();   // NACE version (e.g., 2 for Rev. 2)

Repository Methods

// Get by code and version
$codes->getByCodeAndVersion('6201', 2);
$sections->getByCodeAndVersion('J', 2);
$divisions->getByCodeAndVersion('62', 2);
$groups->getByCodeAndVersion('620', 2);

// Get all by version
$codes->getAllByVersion(2);

// Iteration
foreach ($codes as $code) {
    echo $code->getName();
}

// Count
echo count($codes);

Translator Configuration

use Xterr\NaceCodes\Translation\Adapter\ArrayTranslator;

$translator = new ArrayTranslator(
    ?TranslationLoaderInterface $loader = null,  // Custom loader (optional)
    ?string $defaultLocale = 'en',               // Default locale
    ?string $fallbackLocale = 'en',              // Fallback when translation not found
    ?string $basePath = null                     // Custom translations path
);

$translator->setLocale('de');
$translator->getLocale();              // 'de'
$translator->setFallbackLocale('en');
$translator->getFallbackLocale();      // 'en'
$translator->getAvailableLocales();    // ['bg', 'cs', ...]
