Hi,


what happens if I use this code.

class Foo {

  public $bar;

  public function __construct() {

     $this->bar = array($this, 'baz');
     $this->bar();
  }

  public function bar() {
     echo 'bar';
  }

  public function baz() {
     echo 'baz';
  }
}

new Foo();

What is the output of this snippet?

Are there the same rules as for closures?

Christian


Yes, the same rules.

Hi,

I think for the sake of consistency it should be possible to use the following code.

class Bar {

    public function __construct($dispatcher) {

        $dispatcher->addEventListener('onUpdate', $this->onUpdate);
    }

    public function onUpdate() {}
}

If a property $onUpdate exists then it will be ignored. The same rules as for Closures or for array callbacks.
