In ext\user\theme.php line 136

protected function build_stats(User $duser) {
        global $database;
        global $config;

        $h_join_date = html_escape($duser->join_date);

        $i_image_count = Image::count_images(array("user_id={$duser->id}"));
        $i_favorites_count = Image::count_images(array("favorited_by={$duser->name}"));
        $i_comment_count = Comment::count_comments_by_user($duser);

        $i_days_old = ((time() - strtotime($duser->join_date)) / 86400) + 1;

        $h_image_rate = sprintf("%.1f", ($i_image_count / $i_days_old));
        $h_favorites_rate = sprintf("%.1f", ($i_favorites_count / $i_days_old));
        $h_comment_rate = sprintf("%.1f", ($i_comment_count / $i_days_old));

        $images_link = make_link("post/list/poster=$duser->name/1");

        $comments_link = make_link("post/list/commented_by=$duser->name/1");

        return "
