yii findByAttributes

In most case:

Person::model()->findByAttributes(array('first_name'=>$firstName,'last_name'=>$lastName));

And other uses:

1. Supply a $condition as string:

Person::model()->findByAttributes(    array('first_name'=>$firstName,'last_name'=>$lastName),    'status=1');

2.Supply a $condition as string that contains placeholder and $params as array with placeholder values:

Person::model()->findByAttributes(    array('first_name'=>$firstName,'last_name'=>$lastName),    'status=:status',    array(':status'=>1));

3.Supply a $condition as a CDbCriteria:

$criteria=New CDbCritieria;$critieria->condition='status=1';Person::model()->findByAttributes(    array('first_name'=>$firstName,'last_name'=>$lastName),    $criteria);

4.Supply a $condition as array with property values for CDbCriteria:

Person::model()->findByAttributes(    array('first_name'=>$firstName,'last_name'=>$lastName),    array(        'condition'=>'status=:status',         'params'=>array(':status'=>1)    ));
