Yii Three ways to update counters

Using Yii, there are probably three ways to update counters:

1. Model->save();
2. Model->saveCounters();
3. Model->updateCounters();

For all these methods, we have to get the object before performing the updating process. i.e.,  

$obj = YourObject->model()->findByPk($id);

Difference among them:

1.$obj->visits += 1; 

  $obj->save();

2.$obj->saveCounters(array('visits'=>'1'));

3.$obj->updateCounters(array('visits'=>'1', 'id'=>$id));

The Trick is:

1. Better to use saveCounters()!
2. If you use updateCounters(), pls make sure you have put id in a condition as highlighted in the code. Otherwise, the 'visits' field for all records +1.
