method should not be invoked for some reason (e.g. unauthorized access).

Internationalization (I18N) refers to the process of designing a software application so that
it can be adapted to various languages and regions without engineering changes. For Web
applications, this is of particular importance because the potential users may be from
worldwide.
Yii provides support for I18N in several aspects.
• It provides the locale data for each possible language and variant.
• It provides message and file translation service.
• It provides locale-dependent date and time formatting.
