Какие способы реализации обновления данных реализованы в Active Record Yii2?

In Yii2 Active Record, there are several ways to update data:

1. save() method — if the model already has a primary key (i.e., the record exists in the database), calling save() will update the existing record. You can update all fields or only the changed ones.

2. update() method — updates a record in the database, called on a model instance. You can specify a list of fields to update.

3. updateAll() method — a static method that allows updating multiple records satisfying a condition without loading models into memory.

4. 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.
