Yii Internationalization Library

The package provides common internationalization utilities:

Locale stores locale information created from BCP 47 formatted string. It can parse locale string, modify locale parts, form locale string from parts, and derive fallback locale.
LocaleProvider is a stateful service that stores current locale.

Requirements

PHP 8.0 - 8.5.

Installation

The package could be installed with Composer:

composer install yiisoft/i18n

General usage

Use Locale as follows:

$locale = new \Yiisoft\I18n\Locale('es-CL');
echo $locale->language(); // es
echo $locale->region(); // CL

$locale = $locale->withLanguage('en');
echo $locale->asString(); // en-CL

echo $locale
    ->fallbackLocale()
    ->asString(); // en

Use LocaleProvider as follows:

use \Yiisoft\I18n\LocaleProvider;

final class MyService
{
    public function __construct(
        private LocaleProvider $localeProvider
    ) {    
    }
    
    public function doIt(): void
    {
        $locale = $this->localeProvider->get();
        if ($this->localeProvider->isDefaultLocale()) {
            // ...
        }
        
        // ...        
    }
    
}
