The method of removing the binding behavior of a component in PHP's Yii framework, the YII Framework _php Tutorial

The method of removing the binding behavior of a component in the YII framework of PHP, the YII framework

To remove the behavior, you can call Yii\base\component: the:d Etachbehavior () method is implemented with the name associated with the behavior:

$component->detachbehavior (' MyBehavior1 ');

You can also remove all behaviors:

$component->detachbehaviors ();

Both of these methods will be called to Yii\base\behavior::d Etach (), with the following code:

Public Function Detach () {  //This has to be a famous act of the Lord. Remove the  if ($this->owner) {    //traversal behavior-defined events, one-by-one to dismiss the    foreach ($ This->events () as $event = $handler) {      $this->owner->off ($event, is_string ($handler)? [$this,        $handler]: $handler);    }    $this->owner = null;  }}

In contrast to Yii\base\behavior::attach (), the process of dissolution is to do two things: one is to set the $owner to NULL, indicating that the behavior is not attached to any class. The second is to remove the event Hanlder bound to the class by component off (). In a word, finish.
