cakephp to know the all set variable in controller itself

Question

Can it be possible to track all the set variable by $this->set('variable_name', 'some_value') in the controller's method itself. Actually i have a method that call several other method and each sub method set the value to view. Now I am unable to track if the same key set twice in the main method or not.

example

    function beforeFilter()
{
    $this->set('key1', 'viable value');
}


function reqMethod()
{
    $this->extendMethod1();
    $this->extendMethod2();
    $this->extendMethod3();
    $this->extendMethod4();
    $this->extendMethod5();
    $this->extendMethod6();
            // Want to track all set variable (key) here.
}

private function extendMethod1()
{
    $this->set('key1', 'unknow value');
}

Here it may possible that key1 (by mistake) can be set to another method. Any help really be appreciated.

Answer 1

Controller::set() just adds value(s) to the 'viewVars' property, so to debug all those variables, you'll only have to do this:

debug($this->viewVars);

You could have discovered this yourself, by looking inside the source?
