How to use the var_dump output directly from the controller?

Question

class IndexController extends \Phalcon\Mvc\Controller
{
    public function indexAction()
    {
        $custom = "Custom variable";
        var_dump($custom);
    }
}

How to display the result not using the variables in the template?

P.S. The result of the Echo function is also suppressed. I understand that this is the wrong approach, but it is a quick way to debug the variables.

Answer 1

if you don't see output from controller check if in your template file you have this line:

{{ content() }}

you can use php's var_dump in any place of your code:

var_dump($var);exit;

exit; is to stop anything what happens after this line.

You can also dump your vars in volt's template with volt's function:

{{dump(var)}}

dump() is same as var_dump() Here are some more useful volt functions:
