I'm new to WordPress. I created my first ugly widget. It located in wp-content/plugins/my-awesome-widget/widget_init.php (no more files in this folder). And it's working. I created a sidebar and registered it in functions.php in my theme folder:

function register_page_widgets()
{
    if (function_exists('register_sidebar')) {
        register_sidebar(
            array(
                'name' => 'Page sidebar',
                'id' => 'page_sidebar',
                'description' => '',
                'class' => '',
                'before_widget' => '<div class="page-sidebar">',
                'before_title' => '<div class="title"><span>',
                'after_title' => '</span></div>',
                'after_widget' => '</div>'
            )
        );
    }
}

add_action( 'widgets_init', 'register_page_widgets' );

All widgets, that located in this sidebar, wrapped in elements, that I defined in array: before_widget, before_title etc. Besides my widget. In my code (in widget_init.php) I wrote:

print_r($args);

And I got the result:

Array
(
    [name] => Page sidebar
    [id] => page_sidebar
    [description] => 
    [class] => 
    [before_widget] =>     
    [after_widget] =>     
    [before_title] =>     
    [after_title] =>     
    [widget_id] => my_first_widget
    [widget_name] => My First Widget
)

Somehow before_widget, after_widget, before_title and after_title are empty. What's wrong?

My code:
