CPhpMessageSource uses PHP files and arrays to keep message translations.
- All translations are saved under the basePath directory.
- Translations in one language are kept as PHP files under an individual subdirectory whose name is the same as the language ID. Each PHP file contains messages belonging to the same category, and the file name is the same as the category name.
- Within a PHP file, an array of (source, translation) pairs is returned.
For example:
return array( 'original message 1' => 'translated message 1', 'original message 2' => 'translated message 2', );
Starting from version 1.0.10, messages for an extension class (e.g. a widget, a module) can be specially managed and used. In particular, if a message belongs to an extension whose class name is Xyz, then the message category can be specified in the format of 'Xyz.categoryName'. And the corresponding message file is assumed to be 'BasePath/messages/LanguageID/categoryName.php', where 'BasePath' refers to the directory that contains the extension class file. When using Yii::t() to translate an extension message, we should use: Yii::t('Xyz.categoryName', 'message to be translated').

属性详情
the base path for all translated messages. Defaults to null, meaning the "messages" subdirectory of the application directory (e.g. "protected/messages").
the ID of the cache application component that is used to cache the messages. Defaults to 'cache' which refers to the primary cache application component. Set this property to false if you want to disable caching the messages.
the time in seconds that the messages can remain valid in cache. Defaults to 0, meaning the caching is disabled.

protected string getMessageFile(string $category, string $language)
| ||
$category | string | category name |
$language | string | language ID |
{return} | string | the message file path |
Determines the message file name based on the given category and language. If the category name contains a dot, it will be split into the module class name and the category name. In this case, the message file will be assumed to be located within the 'messages' subdirectory of the directory containing the module class file. Otherwise, the message file is assumed to be under the basePath.
public void init()

Initializes the application component. This method overrides the parent implementation by preprocessing the user request data.
protected array loadMessages(string $category, string $language)
| ||
$category | string | the message category |
$language | string | the target language |
{return} | array | the loaded messages |
Loads the message translation for the specified language and category.
