phpdot/i18n
===========

[](#phpdoti18n)

Internationalization built on ICU MessageFormat (via `ext-intl`): one syntax for interpolation, pluralization, and selection. Translations load through pluggable loaders (PHP arrays, JSON, or a chain), compiled maps are cached through any PSR-16 cache, and the translator implements the `PHPdot\Contracts\I18n\MessageTranslatorInterface` so the rest of the ecosystem depends only on the contract.

Requirements
------------

[](#requirements)

RequirementConstraintPHP`>= 8.5``ext-intl``*``phpdot/contracts``^0.1``psr/simple-cache``^3.0``phpdot/container` is a dev-only suggestion — the `#[Config('i18n')]` / binding attributes are inert until a phpdot application reflects them.

Installation
------------

[](#installation)

```
composer require phpdot/i18n
```

Usage
-----

[](#usage)

```
use PHPdot\I18n\I18nConfig;
use PHPdot\I18n\Translator;
use PHPdot\I18n\Loader\PhpArrayLoader;

$config = new I18nConfig(
    default: 'en',
    supported: ['en', 'ar', 'fr'],
    path: '/app/lang',
);

$translator = new Translator(
    loader: new PhpArrayLoader($config),
    cache: $cache,   // any PSR-16 implementation
    config: $config,
);

$translator->setLocale('ar_JO');
echo $translator->translate('messages.welcome', ['name' => 'Omar']);
```

### Translation files

[](#translation-files)

Keys are prefixed by filename, so `lang/en/messages.php` gives `messages.welcome`:

```
// lang/en/messages.php
return [
    'welcome' => 'Welcome, {name}!',
    'items' => '{count, plural, one {# item} other {# items}}',
];
```

`JsonLoader` reads the same shape from `.json` files; `ChainLoader` layers several loaders so later sources (e.g. database overrides) win. Every template is ICU MessageFormat — interpolation, `plural`, and `select` all share one syntax — and `ICUValidator` can check a template before it ships.

Architecture
------------

[](#architecture)

`Translator` resolves a key to its ICU template through the configured `LoaderInterface`, formats it with the current locale using `ext-intl`'s MessageFormatter, and caches the compiled per-language map in a PSR-16 cache. Unknown keys are recorded so missing translations can be audited.

 ```
