Summary of usage of YII path

In yii, if it is//, protected/views/layouts will be debugged by default, and//represents the absolute path. This is actually the absolute and relative relationship/represents the relative path, such as layout under module/user. If you use a single slash, you will first find view under the currently activated module by default. If there is no currently activated module, you will start to find it from the root directory of the system. If you use a double slash, you will start to find it directly from the root of the system

Yii framework already defined namespace constants:

system: Point to the Yii Framework Directory; YII\ framework
zii: Point to the zii library directory; YII\ framework\ zii
application: Points to the application base directory; protected\
webroot: Points to the directory that contains the entry script files. This alias has been in effect since version 1.0. 3.\
ext: Points to the directory containing all third-party extensions, available from version 1.0. 8; \ protected\ extensions

Yii::getPathOfAlias('zii') 
Yii::import ('zii.*')  
Yii::setPathOfAlias('backend', $backend); 
'import' => array( 
'backend.models.*',  

The application home directory refers to the root directory containing all PHP codes and data with high safety factor. By default, this directory 1 is one of the directories where the entry code resides: protected. This path can be changed by setting basePath in application configuration.
