Render array to markup after submitting a form

Question

In my Drupal 7 custom moudle, i would like to output result of form as an formatted array. Simmilar like you can print_r or printf arrays.

 $form['results'] = array(
            '#type'     => 'item',
            '#markup'   => $form_state['temporary']
)

so $form_state['temporary'] is array, but i do not want "array" text to show up but formatted array representation, whatewer is in it.

Thanks!

Just try like:

'#markup' => '<pre>'.print_r($form_state['temporary'], true).'</pre>';

you could just save the print_r() value to variable and then output that to a Div or something ...
