Я расширил Zend_Currency и переписал методы getName() и getSymbol(), чтобы они (как и Zend_Currency при изменении локали, чего мы не хотим ...) возвращают «свежие» данные из Zend_Locale_Data каждый раз, когда я делаю запрос.
В приведенном ниже примере класса вы можете создать экземпляр Default_Model_Currency() и установить для параметра валюты значение любой действительной валюты (например, EUR, USD и т. Д.), Сохраняя тот же языковой стандарт.
