CPhpMessageSource represents a message source that stores translated messages in PHP scripts.

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',
    );
    
When cachingDuration is set as a positive number, message translations will be cached.

Property Details

basePath property
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").

cachingDuration property
public integer $cachingDuration;

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

Method Details

init() method
public void init()

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

loadMessages() method
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.
