Drupal: Add "Number of Items Displayed" in Views Page

In template.php you have to write


function template_preprocess_views_view(&$variables){
    if($variables['name']=='my_view'){
        $current_page=intval($variables['view']->get_current_page());
        $items_per_page=intval($variables['view']->get_items_per_page());
        $item_displayed_start=($items_per_page*$current_page)+1;
        $item_displayed_end=($items_per_page*($current_page+1));
        $total_items=intval($variables['view']->query->pager->total_items);
        if($total_items==0){
            $item_displayed_start=$total_items;
        }
        if($item_displayed_end>$total_items){
            $item_displayed_end=$total_items;
        }
        $variables['displayed_items']="(Displaying $item_displayed_start - $item_displayed_end of $total_items)";
    }
}


And use $displayed_items variable in views-view.tpl.php.
