How to remove the behavior bound to a component in PHP's Yii framework, yii framework_PHP tutorial

The method of removing the behavior bound to the component in PHP's Yii framework, yii framework

To remove the behavior, you can call the yiibaseComponent::detachBehavior() method to use the behavior-related Joint name implementation:

$component->detachBehavior('myBehavior1');

You can also remove all behaviors:

$component->detachBehaviors();

The above two methods will call yiibaseBehavior::detach(), the code is as follows:

public function detach()
{
  // 这得是个名花有主的行为才有解除一说
  if ($this->owner) {

    // 遍历行为定义的事件，一一解除
    foreach ($this->events() as $event => $handler) {
      $this->owner->off($event, is_string($handler) ? [$this,
        $handler] : $handler);
    }
    $this->owner = null;
  }
}

Contrary to yiibaseBehavior::attach(), the process of unblocking is to do two things: First, set $owner to null , indicating that this behavior is not attached to any class. The second is to release the event handler bound to the class through Component's off(). In a word, start well and end well.
