PHP Calling a class function from within a anonymous function

Question

How do I call the doSomethingElse function from within this anonymous function?

If I try $this->doSomethingElse() I get 'Using $this when not in object context ' error

class MyController extends AppController {

    public function doSomethingElse()
    {
        //do something
    }


    public function doSomething()
    {
        $this->Crud->on('afterSave', function(CakeEvent $event) {
            if ($event->subject->success) {

                    //how do I call 'doSomethingElse' from here

            }
        }); 
    }
}

This is not valid code, it's unclear what you're asking exactly. — deceze

make a reference to your MyController outside your anonymous function and use this like

class MyController extends AppController {

    public function doSomethingElse()
    {
        //do something
    }


    public function doSomething()
    {
        $reference = $this;

        $this->Crud->on('afterSave', function(CakeEvent $event) use ($reference) {
            if ($event->subject->success) {

                    //how do I call 'doSomethingElse' from here
                    $reference->doSomethingElse();

            }
        }); 
    }
}

After PHP5.4 $this can be used in anonymous functions instead pass it as a reference in use (...).
