CGettextMessageSource represents a message source that is based on GNU Gettext.

Each CGettextMessageSource instance represents the message tranlations for a single domain. And each message category represents a message context in Gettext. Translated messages are stored as either a MO or PO file, depending on the useMoFile property value.

All translations are saved under the basePath directory. Translations in one language are kept as MO or PO files under an individual subdirectory whose name is the language ID. The file name is specified via catalog property, which defaults to 'messages'.

属性详情

basePath 属性
public string $basePath;

the base path for all translated messages. Defaults to null, meaning the "messages" subdirectory of the application directory (e.g. "protected/messages").

cacheID 属性 (自版本 v1.0.10 可用)
public string $cacheID;

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.

cachingDuration 属性
public integer $cachingDuration;

the time in seconds that the messages can remain valid in cache. Defaults to 0, meaning the caching is disabled.

catalog 属性
public string $catalog;

the message catalog name. This is the name of the message file (without extension) that stores the translated messages. Defaults to 'messages'.

useBigEndian 属性
public boolean $useBigEndian;

whether to use Big Endian to read and write MO files. Defaults to false. This property is only used when useMoFile is true.

useMoFile 属性
public boolean $useMoFile;

whether to load messages from MO files. Defaults to true. If false, messages will be loaded from PO files.

方法详情

init() 方法
public void init()

Initializes the application component. This method overrides the parent implementation by preprocessing the user request data.

loadMessages() 方法
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.
