composer require tobento/app-language

Requirements

PHP 8.4 or greater

Documentation

App

Check out the App Skeleton if you are using the skeleton.

You may also check out the App to learn more about the app in general.

Language Boot

The language boot does the following:

installs and loads language config file
language interfaces implementation based on config
determines current language
sets current language on the date formatter

use Tobento\App\AppFactory;

// Create the app
$app = new AppFactory()->createApp();

// Add directories:
$app->dirs()
    ->dir(realpath(__DIR__.'/../'), 'root')
    ->dir(realpath(__DIR__.'/../app/'), 'app')
    ->dir($app->dir('app').'config', 'config', group: 'config')
    ->dir($app->dir('root').'public', 'public')
    ->dir($app->dir('root').'vendor', 'vendor');

// Adding boots:
$app->boot(\Tobento\App\Language\Boot\Language::class);

// Run the app:
$app->run();

Language Config

The configuration for the language is located in the app/config/language.php file at the default App Skeleton config location.

App Languages

use Tobento\App\AppFactory;
use Tobento\Service\Language\LanguagesInterface;

$app = new AppFactory()->createApp();

// Add directories:
$app->dirs()
    ->dir(realpath(__DIR__.'/../'), 'root')
    ->dir(realpath(__DIR__.'/../app/'), 'app')
    ->dir($app->dir('app').'config', 'config', group: 'config')
    ->dir($app->dir('root').'public', 'public')
    ->dir($app->dir('root').'vendor', 'vendor');

// Adding boots:
$app->boot(\Tobento\App\Language\Boot\Language::class);
$app->booting();

// Gets the app languages:
$languages = $app->get(LanguagesInterface::class);

// Run the app:
$app->run();

You may check out the Language Service to learn more about it.

Current And Default App Language

use Tobento\App\AppFactory;
use Tobento\Service\Language\LanguagesInterface;
use Tobento\Service\Language\LanguageInterface;

$app = new AppFactory()->createApp();

// Add directories:
$app->dirs()
    ->dir(realpath(__DIR__.'/../'), 'root')
    ->dir(realpath(__DIR__.'/../app/'), 'app')
    ->dir($app->dir('app').'config', 'config', group: 'config')
    ->dir($app->dir('root').'public', 'public')
    ->dir($app->dir('root').'vendor', 'vendor');

// Adding boots:
$app->boot(\Tobento\App\Language\Boot\Language::class);
$app->booting();

// Gets the app languages:
$languages = $app->get(LanguagesInterface::class);

// Current language:
$currentLanguage = $languages->current();
// var_dump($currentLanguage instanceof LanguageInterface);
// bool(true)

// Default language:
$defaultLanguage = $languages->default();
// var_dump($defaultLanguage instanceof LanguageInterface);
// bool(true)

// Run the app:
$app->run();

You may check out the Language Service to learn more about it.

Resolving Current Language

By default, the current language is resolved by the Tobento\App\Language\CurrentLanguageRouterResolver::class. You may change the implementation in the language config.

Localizing Routes

You may localize your routes by the following way:

use Tobento\App\AppFactory;
use Tobento\App\Language\RouteLocalizerInterface;
use Tobento\Service\Language\LanguagesInterface;

$app = new AppFactory()->createApp();

// Add directories:
$app->dirs()
    ->dir(realpath(__DIR__.'/../'), 'root')
    ->dir(realpath(__DIR__.'/../app/'), 'app')
    ->dir($app->dir('app').'config', 'config', group: 'config')
    ->dir($app->dir('root').'public', 'public')
    ->dir($app->dir('root').'vendor', 'vendor');

// Adding boots:
$app->boot(\Tobento\App\Language\Boot\Language::class);
$app->booting();

// Localize Routes:
$routeLocalizer = $app->get(RouteLocalizerInterface::class);

$route = $app->route('GET', '{?locale}/team', function(LanguagesInterface $languages): array {
    return ['page' => 'team', 'locale' => $languages->current()->locale()];
})->name('team');

$routeLocalizer->localizeRoute($route);

/*
print_r($app->routeUrl('team')->translated());
Array
(
    [de] => https://example.com/de/team
    [en] => https://example.com/team
)
*/

// Run the app:
$app->run();

Translation Routing

Simply, install the App Translation bundle and boot the \Tobento\App\Translation\Boot\Translation::class:

composer require tobento/app-translation

use Tobento\App\AppFactory;
use Tobento\App\Language\RouteLocalizerInterface;
use Tobento\Service\Language\LanguagesInterface;
use Tobento\Service\Translation\TranslatorInterface;
use Tobento\Service\Translation\Resource;

$app = new AppFactory()->createApp();

// Add directories:
$app->dirs()
    ->dir(realpath(__DIR__.'/../'), 'root')
    ->dir(realpath(__DIR__.'/../app/'), 'app')
    ->dir($app->dir('app').'config', 'config', group: 'config')
    ->dir($app->dir('root').'public', 'public')
    ->dir($app->dir('root').'vendor', 'vendor');

// Adding boots:
$app->boot(\Tobento\App\Language\Boot\Language::class);
$app->boot(\Tobento\App\Translation\Boot\Translation::class);
$app->booting();

// Add routes translations:
$app->on(TranslatorInterface::class, function(TranslatorInterface $translator) {
    $translator->resources()->add(new Resource(
        name: 'routes',
        locale: 'en',
        translations: [
            'checkout' => 'checkout', 'payment' => 'payment',
            'products' => 'products', 'edit' => 'edit'
        ],
    ));
    $translator->resources()->add(new Resource(
        name: 'routes',
        locale: 'de',
        translations: [
            'checkout' => 'kasse', 'payment' => 'zahlung',
            'products' => 'produkte', 'edit' => 'bearbeiten',
        ],
    ));
});

// Localize Routes:
$routeLocalizer = $app->get(RouteLocalizerInterface::class);

$route = $app->route('GET', '{?locale}/{checkout}/{payment}', function(LanguagesInterface $languages) {
    return ['page' => 'checkout', 'locale' => $languages->current()->locale()];
})->name('checkout.payment');

// checkout and payment will be translated
// by the TranslatorInterface::class if implemented, otherwise
// checkout and payment is used:
$routeLocalizer->localizeRoute($route, 'checkout', 'payment');

/*
print_r($app->routeUrl('checkout.payment')->translated());
Array
(
    [de] => https://example.com/de/kasse/zahlung
    [en] => https://example.com/checkout/payment
)
*/

// Resource example:
$routeResource = $app->routeResource('{?locale}/{products}', ResourceController::class)->name('products');

$routeLocalizer->localizeRoute($routeResource, 'products', 'edit.edit');
// define resource verbs with a dot if you want to translate them too!
// e.g. 'create.create' or 'edit.edit'

/*
print_r($app->routeUrl('products.edit', ['id' => 5])->translated());
Array
(
    [de] => https://example.com/de/produkte/5/bearbeiten
    [en] => https://example.com/products/5/edit
)
*/

// Run the app:
$app->run();

By default, translations are loaded from the routes named resources.

You may change the localization strategy by changing the RouteLocalizerInterface::class implemenation in the language config file.

Localizing Routes With Domains

You will need to specify the languages with its domain in the app/config/language.php file:

// ...
$storage = new InMemoryStorage([
    'languages' => [
        1 => [
            'id' => 1,
            'locale' => 'de-DE',
            
            // The key is used for translations and storing resources!
            'key' => 'de',
            
            'domain' => 'example.de',
            'default' => true,
        ],
        2 => [
            'id' => 2,
            'locale' => 'de-CH',
            
            // The key is used for translations and storing resources!
            'key' => 'de',
            // or if specific translations and storing resources!
            //'key' => 'de-CH',
            
            'slug' => 'de',
            'domain' => 'example.ch',
            'fallback' => 'de-DE',
            'default' => true,
        ],
        3 => [
            'id' => 3,
            'locale' => 'fr-CH',
            'slug' => 'fr',
            'domain' => 'example.ch',
            'fallback' => 'de-DE',
        ],
    ],
]);
// ...
