// create a new Zend_Locale object for the target language $locale = new Zend_Locale('fr_FR'); // create a new Zend_Translate object using the gettext adapter and the target language $translate = new Zend_Translate(array( 'adapter' => 'gettext', 'content' => '/path/to/messages.mo', 'locale' => $locale )); // translate the message using the getTranslation method $msg = $translate->getTranslation('Hello, World!'); // output the translated message echo $msg;In this example, we first create a new Zend_Locale object with the target language set to French (fr_FR). We then create a new Zend_Translate object with the gettext adapter and the target language set to the same French locale. Finally, we call the getTranslation method on the Zend_Translate object with the message we want to translate ('Hello, World!'), which returns the translated string. Overall, Zend_Locale is a powerful library for managing localized resources in PHP, and the getTranslation method is just one of many tools that it provides for this purpose.
