The Locale Component¶
Locale component provides fallback code to handle cases when theintl
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);
- Install it via PEAR ( pear.symfony.com/Locale);
- Install it via Composer (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'));
}
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::getIcuVersion();
$icuDataVersion = Locale::getIcuDataVersion();
