The Locale Component

Locale component provides fallback code to handle cases when the intl extension is missing. Additionally it extends the implementation of a native :phpclass:`Locale` class with several handy methods.

Replacement for the following functions and classes is provided:

• :phpfunction:`intl_is_failure`
• :phpfunction:`intl_get_error_code`
• :phpfunction:`intl_get_error_message`
• :phpclass:`Collator`
• :phpclass:`IntlDateFormatter`
• :phpclass:`Locale`
• :phpclass:`NumberFormatter`

Note

Stub implementation only supports the en locale.

Installation

You can install the component in many different ways:

• Use the official Git repository (https://github.com/symfony/Locale);
• :doc:`Install it via Composer</components/using_components>` (symfony/locale on Packagist).

Usage

Taking advantage of the fallback code includes requiring function stubs and adding class stubs to the autoloader.

When using the ClassLoader component following code is sufficient to supplement missing intl extension:

if (!function_exists('intl_get_error_code')) {
    require __DIR__.'/path/to/src/Symfony/Component/Locale/Resources/stubs/functions.php';

    $loader->registerPrefixFallbacks(
        array(__DIR__.'/path/to/src/Symfony/Component/Locale/Resources/stubs')
    );
}

:class:`Symfony\\Component\\Locale\\Locale` class enriches native :phpclass:`Locale` class with additional features:

use Symfony\Component\Locale\Locale;

// Get the country names for a locale or get all country codes
$countries = Locale::getDisplayCountries('pl');
$countryCodes = Locale::getCountries();

// Get the language names for a locale or get all language codes
$languages = Locale::getDisplayLanguages('fr');
$languageCodes = Locale::getLanguages();

// Get the locale names for a given code or get all locale codes
$locales = Locale::getDisplayLocales('en');
$localeCodes = Locale::getLocales();

// Get ICU versions
$icuVersion = Locale::getIntlIcuVersion();
$icuDataVersion = Locale::getIcuDataVersion();
