I have this code but I am stuck...

```
$my_var = function (){

  return array('hello you');
};

var_dump($my_var); // returns object(Closure)#2 (0) { }

```

how do I `echo $my_var`?

I would assume it would be `echo $my_var[0]`; but this does not work.

`Fatal error: Cannot use object of type Closure as array in ...`
