Table prefix is defined using Gii by setting to tbl_. Once you set it, UserController will get generated instead of TblUserController.

The Yii Framework includes a class naming convention in which the names of classes map to the directories where they are stored. For your information, “framework/” directory is the root level directory of Yii that stores all classes hierarchically. Also, in Yii, the class names may contain only alphanumeric characters. Though numbers are allowed but are discouraged. You can use Dot (.) just in place of path separators.
