File Translation
File translation is accomplished by calling CApplication::findLocalizedFile(). Given the path
of a file to be translated, the method will look for a file with the same name under the
LocaleID subdirectory. If found, the file path will be returned; otherwise, the original file
path will be returned.
File translation is mainly used when rendering a view. When calling one of the render
methods in a controller or widget, the view files will be translated automatically. For
example, if the target language is zh_cn while the source language is en_us, rendering a
view named edit would resulting in searching for the view file protected/views/ControllerID/
zh_cn/edit.php. If the file is found, this translated version will be used for rendering;
otherwise, the file protected/views/ControllerID/edit.php will be rendered instead.
File translation may also be used for other purposes, for example, displaying a translated
image or loading a locale-dependent data file.
Date and Time Formatting
Date and time are often in different formats in different countries or regions. The task of
date and time formatting is thus to generate a date or time string that fits for the specified
locale. Yii providesCDateFormatter for this purpose.
Each CDateFormatter instance is associated with a target locale. To get the formatter
associated with the target locale of the whole application, we can simply access the
dateFormatter property of the application.
