ext: Point 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's home directory is the root directory of PHP code and data that contains all the higher safety factors. By default, this directory is usually a directory in the directory where the entry code is located: protected. This path can be changed by setting BasePath in the application configuration.

Yii::getframeworkpath () {Full URL}

Protected/venders directory:

Yii::import (' application.venders.* ');  

or in protected/config/main.php description:

' Import ' =>array (...      ') Application.venders.* ',
