Register an event handler at Object-Level
e.g inside the init method of a Model
// this should be inside your model class. For example User.php
public function init(){
$this->on(self::EVENT_NEW_USER, [$this, 'sendMail']);
$this->on(self::EVENT_NEW_USER, [$this, 'notification']);
// first parameter is the name of the event and second is the handler.
// For handlers I use methods sendMail and notification
// from $this class.
parent::init(); // DON'T Forget to call the parent method.
}

Register an event handler at Class-Level
To register event handles at Class-Level a good place can be inside the bootstrap process.
So, you can put the registration code as
Event::on(ActiveRecord::className(), ActiveRecord::EVENT_AFTER_INSERT, function ($event) {
Yii::debug(get_class($event->sender) . ' is inserted');
});
in a php file like the bootstrap.php
used in Advanced-Template or through configuration, with your custom component for example
