For example, [enabling gzip](http://www.yiiframework.com/doc/cookbook/39/) compression on the output could be done via extending CWebApplication. But because there are entry points for event handlers, one can do this:


```php
Yii::app()->onbBeginRequest = create_function('$event', 'return ob_start("ob_gzhandler");'), Yii::app()->oneEndRequest = create_function('$event', 'return ob_end_flush();'),
```
[...]
So, in this case, you are extending the functionality of an object with functionality of another object.

After studying this cookbook page you are encouraged to reread the [corresponding guide page](http://www.yiiframework.com/doc/guide/basics.component) as it contains advanced information (for example, if you are familiar with interfaces, you might find it enough to implement IBehavior before extending CBehavior).
