Because Yii intends to be integrated nicely with third-party libraries, it does not define any global functions. Everything in Yii needs to be addressed with full class name or object scopes. For example, to access the current user, we need to use Yii::app()->user; to access application parameters, we need Yii::app()->params['name']; and so on. While editors like textmate can help alleviate the problem of these lengthy typings, it is worthwhile to define global shortcut functions to some commonly used method calls. They will make the application code look cleaner.

Most controls that are rendered by CHtml have an argument called $htmlOptions. This argument is an array that holds the attributes of the HTML element. For example the following code:

With yii you're able to create ajax requests and updates easily. But most times you always want to show a loading indicatior to your user.
