为什么yii中的布局字符串前面有两个斜杠？

Question

When I create a new Yii application using the yii webapp [my_application] command, it creates a folder with a bunch of files and folders in it. One of those files is the Controller component which extends the CController. Inside the Controller class, the layout property is declared as such:

public $layout='//layouts/column1';

My question is: Why is there two slashes in front of the layout string?

Answer 1

Two slashes refer to the views root folder.
