Translation Laravel Package
symfony/translation
Symfony Translation component helps internationalize PHP apps with a powerful Translator, loaders, and resources (arrays, files, etc.). Define locales, add message catalogs, and translate strings with parameters and pluralization support across your application.
Provides tools to internationalize your application
Frequently asked questions about Translation
- How do I integrate Symfony Translation into Laravel without conflicts?
- Symfony Translation is framework-agnostic and PSR-compliant, so it integrates cleanly with Laravel’s service container. Register the Translator as a singleton in your `AppServiceProvider` and bind it to Laravel’s config. Avoid conflicts by using a custom `TranslationServiceProvider` to manage locale-specific configurations and loaders.
- Can I use Symfony Translation with Laravel’s Blade templates?
- Yes, you can alias Symfony’s `trans()` method to Laravel’s existing `Lang::trans()` or extend it to support advanced features like pluralization and interpolation. For Blade, use `@translate` directives or pass the Translator instance to your views via shared data.
- What Laravel versions support Symfony Translation?
- Symfony Translation works with Laravel 8.x, 9.x, and 10.x due to its PSR-compliant design. Ensure your Laravel app meets Symfony Translation’s PHP 8.0+ requirement. No framework-specific dependencies mean backward compatibility is rarely an issue.
- How do I migrate from Laravel’s built-in Lang::get() to Symfony Translation?
- Use a custom CLI tool (e.g., `TranslationMigrator`) to convert Laravel’s JSON/YAML translation files to Symfony’s supported formats (XLIFF, YAML, Array). Bind the new Translator to your container and update Blade templates to use `trans()` or `@translate`. Test thoroughly with a subset of locales first.
- Does Symfony Translation support dynamic database-backed translations?
- Yes, Symfony Translation supports database-backed translations via the `DatabaseLoader`. Store translations in a table (e.g., `translations`) with columns for `locale`, `domain`, and `message`, then configure the loader in Laravel’s service container. Cache results in Redis for performance.
- How do I handle pluralization for non-English locales in Laravel?
- Symfony Translation uses ICU MessageFormat for pluralization, supporting 100+ locales out of the box. For edge cases (e.g., Arabic, Russian), extend the `MessageSelector` or use custom rules. Example: `{{ $translator->trans('You have %count% message(s).', ['%count%' => 5], 'messages', 'en_US') }}`.
- What’s the best way to cache translations in Laravel for performance?
- Symfony’s `MessageCatalogue` caches translations in memory by default. For Laravel, extend caching with Redis via the `CacheAdapter` or OPcache. Benchmark file vs. database loaders for large catalogs (>50K strings) and use Redis for shared caching across queues/workers.
- Can I use Symfony Translation with Laravel’s Inertia.js or API-driven frontend?
- Yes, pass the Translator instance to your frontend via API endpoints (e.g., `/api/translations/{locale}`) or share it in state management (Pinia, Zustand). For Inertia.js, include translations in page props or fetch them dynamically. Use HTTP caching for static locales.
- How do I validate translations for missing keys or syntax errors in CI?
- Use Symfony’s `TranslationChecker` in your CI pipeline to scan translation files for missing keys, syntax errors, or unused entries. Integrate it with Laravel’s `Artisan` commands or Git hooks. Example: `php artisan translation:check --locale=fr_FR --domain=validation`.
- What are the alternatives to Symfony Translation for Laravel, and when should I choose them?
- Alternatives include Laravel’s built-in `Lang::get()` (simpler but limited), `spatie/laravel-translatable` (for model attributes), or `laravel-localization` (for route/locale handling). Choose Symfony Translation if you need advanced features like pluralization, interpolation, or multi-format loaders. For model translations, combine it with `spatie/laravel-translatable`.
