Answer from AI
In Yii2 Active Record, there are several ways to update data:
-
save()method — if the model already has a primary key (i.e., the record exists in the database), callingsave()will update the existing record. You can update all fields or only the changed ones. -
update()method — updates a record in the database, called on a model instance. You can specify a list of fields to update. -
updateAll()method — a static method that allows updating multiple records satisfying a condition without loading models into memory. -
updateAllCounters()method — updates numeric fields by increasing or decreasing their values, also without loading models.
Example of using updateAll():
// Update the status of all users with the role 'guest'
User::updateAll(['status' => User::STATUS_ACTIVE], ['role' => 'guest']);
Thus, Yii2 provides both updating through model instances and bulk updating via static methods.
