Question

What is the difference between homeUrl and baseUrl in Yii framework?

Answer 1

Yii::app()->getBaseUrl(true);   // => http://localhost/yii_projects
Yii::app()->getHomeUrl();       // => /yii_projects/index.php
Yii::app()->getBaseUrl(false);  // => /yii_projects

This is the best practice in pointing directory of images etc. or the file itself rather than hardcoding the path which can change name"
