/**
 * Retrieve values from a model and recurse its children to build a data structure
 * 
 * @param  Model $model 
 * @return array
 */

The recurseModel(Model $model) function in Zend\View\Renderer\JsonRenderer does not return an array. instead it returns:

Zend\View\Variables Object
(
    [strictVars:protected] => 
    [storage:ArrayObject:private] => Array
        (
            [content] => Array
                (
                    [test] => json
                )

        )
