The Locale Component
Locale component provides fallback code to handle cases when the
intlextension is missing. Additionally it extends the implementation of a native Locale class with several handy methods.
Replacement for the following functions and classes is provided:
- intl_is_failure
- intl_get_error_code
- intl_get_error_message
- Collator
- IntlDateFormatter
- Locale
- NumberFormatter
Note
Stub implementation only supports the en locale.
Installation
You can install the component in 2 different ways:
- Use the official Git repository (https://github.com/symfony/Locale);
- Install it via Composer (
symfony/localeon 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:
1 2 3 4 5 6 7
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')
);
}Locale class enriches native Locale class with additional features:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
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();
