function widget_dailytopten_init() {
        if(!function_exists('register_sidebar_widget')) { return; }
        function widget_dailytopten($args) {
		echo $before_title
                      . 'My widget'
                      . $after_title;

			Hello widget!
        }
        register_sidebar_widget('My sidget','widget_dailytopten');
    }
add_action('plugins_loaded', 'widget_dailytopten_init');
