On the same basis, as above, if a particular cookie does not exists, a corresponding object (CHttpCookie instance) for it will not be created! Trying to read such cookie will result in error "Trying to get property of non-object". To avoid that, it is always better to read a cookie using ternary operator, like that:


```php
$cookie = (isset(Yii::app()->request->cookies['cookie_name']->value)) ? Yii::app()->request->cookies['cookie_name']->value : '';
```
[...]
```php
$is_cookie = !emptyisset(Yii::app()->request->cookies['cookie_name']->value);
```
