You can set the default languages in the config/main.php as

return array(
    ...
    'sourceLanguage' => 'fr',
    'language'=>'en',
    ...
    'params' => array(
               ...
               'languages'=>array('en_us'=>'English', 'fr'=>'French', 'fa_ir'=>'فارسی'),
               ....
               ), 
); 

and change your language everywhere you like:

Yii::app()->language = Yii::app()->params->languages['fa_ir'];

also for more experience, maybe:

Yii::app()->language = Yii::app()->params->languages[$_GET['lang']];
