Can't execute a function

[NotionCommotion]

Why am I not able to execute $container2['hello']($container2)?

$container1['hello'] = function ($c) {
    return 'hello 1 '.print_r($c,1);
};
var_dump($container1['hello']($container1));

$app = new \Slim\App();
$container2 = $app->getContainer();
$container2['hello'] = function($c) {
    return 'hello 2 '.print_r($c,1);
};
var_dump($container2['hello']($container2));

string(178) "hello 1 Array
(
    [hello] => Closure Object
        (
            [parameter] => Array
                (
                    [$c] => <required>
                )

        )

)

Recall my post in one of your other threads

 

In the case of your factory function service, you need to either pass a function that returns the factory function, or use the protect helper method.

If you want to define a function as a service, use the protect to prevent Pimple from executing it as the service constructor.

Thanks Kicken,

 

Yes, I do recall your earlier response to one of my other threads!  And I am sure your response addresses the particular pimple/slim classes.

 

I am still confused, however, how I can assign a function to two different array elements, and one exists and the other does not.  I expect it has to do with those damn magic methods.
