Answer / Abhishek Verma
In Yii2, you can use the ActiveRecord's delete(), insert(), and save() methods for CRUD operations. Here's an example:
```php
// For deleting a record:
$model->delete();
// For creating (inserting) a new record:
$newModel = new ModelName;
$newModel->attribute1 = 'value1';
$newModel->save();
// For updating (saving) an existing record:
$existingModel = ModelName::findOne($id);
$existingModel->attribute1 = 'value1';
$existingModel->save();
```
