Locale Component ================ Locale provides fallback code to handle cases when the ``intl`` extension is missing. Loading the fallback classes for example using the ClassLoader component only requires adding the following lines to your autoloader: // intl if (!function_exists('intl_get_error_code')) { require __DIR__.'/../vendor/symfony/src/Symfony/Component/Locale/Resources/stubs/functions.php'; $loader->registerPrefixFallback(__DIR__.'/../vendor/symfony/src/Symfony/Component/Locale/Resources/stubs'); } Resources --------- You can run the unit tests with the following command: phpunit
