Jumble text in yii

Is there some function in yii which allows me to replace my text like if I have "How Are you?" in my database column when I retrieve it in my site it should be jumbled like "dszxfdafdfdfdsvw" ?

doesn’t matter to yii , just use php replace() or preg_replace()…function ,the mysql also have the string replace functionality . the place you can do : in view file or CActiveRecord::afterFind() :D
