I was looking for a Yii file helper to make reading and writing easier. But I could not find anything, and it looks strange. Is there any functionality for this in Yii?
Yii has only CFileHelper. But it does not support reading and writing. http://www.yiiframework.com/doc/api/1.1/CFileHelper
There is an extension called http://www.yiiframework.com/extension/cfile/ that has some relevant methods that you may need.
