Answer 1

A recursive function for a change;) I use it to output the media information for videos etc elements of which can use nested array / attributes.

function custom_print_array($arr = array()) {
    $output = '';
    foreach($arr as $key => $val) {
        if(is_array($val)){
            $output .= '
' . ucwords(str_replace('_',' ', $key)) . ':
' . custom_print_array($val) . '
' . '
';
        }
        else {
            $output .=  '
' . ucwords(str_replace('_',' ', $key)) . ': ' . $val . '
';
        }
    }
    return $output;

}
