最近我在开发ShuK-ON!主题时想加一个文章浏览次数统计的功能，以下代码即可实现；
代码放进functions.php，然后就可以在文章页通过输出统计次数。

function getViewsStr($widget, $format = "{views}") {
    $fields = unserialize($widget->fields);
    if (array_key_exists('views', $fields)) {
        $views = (!empty($fields['views'])) ? intval($fields['views']) : 0;
    } else {
        $views = 0;
    }
    if ($widget->is('single')) {
        $views = $views + 1;
        $widget->setField('views', 'str', strval($views), $widget->cid);
    }
    return str_replace("{views}", $views, $format);
}

通过记录Cookies浏览过的文章，下次访问就不再统计

function getViewsStr($widget, $format = "{views}") {
    $fields = unserialize($widget->fields);
    if (array_key_exists('views', $fields)) {
        $views = (!empty($fields['views'])) ? intval($fields['views']) : 0;
    } else {
        $views = 0;
    }
    if ($widget->is('single')) {
        $vieweds = Typecho_Cookie::get('contents_viewed');
        if (empty($vieweds)) {
            $vieweds = array();
        } else {
            $vieweds = explode(',', $vieweds);
        }
        if (!in_array($widget->cid, $vieweds)) {
            $views = $views + 1;
            $widget->setField('views', 'str', strval($views), $widget->cid);
            $vieweds[] = $widget->cid;
            $vieweds = implode(',', $vieweds);
            Typecho_Cookie::set("contents_viewed", $vieweds);
        }
    }
    return str_replace("{views}", $views, $format);
}
