Yii is one of the best PHP frameworks out there, and it really does a lot of stuff pretty awesome. One of the things that is built right into the core functionality of Yii is CDbCriteria class, which helps you manage your queries whenever you want to select data from a database.

The criteria object is especially useful in combination with the various find methods of active records. This way you get powerful and customizable methods to get data rightout of Yii for free.


Here is an example of how to use the criteria object to specifcy your query

$criteria = new CDbCriteria;
$criteria->condition='post_id=:post_id AND status=:status';
$criteria->params=array(':post_id'=>8, ':status'=>'active');
$post = Post::model()->find($criteria);
