memcache yii framework usage

这篇文章主要介绍了Yii框架中memcache用法,以实例形式分析了在Yii框架中加入memcache的具体操作方法,是非常实用的技巧,需要的朋友可以参考下

本文实例讲述了Yii框架中memcache用法。分享给大家供大家参考。具体分析如下:

在现在的公司用的是YII的框架,接触到的东西也比较多,可以学到的东西也比较多,在以前的公司没有接触过memcache,只是听过,但是从来没有真正用过。现在终于有机会使用一下了,就以我做的项目为例吧!

我做的项目是一个手机排行榜,但是排行榜每隔15分钟刷新一次啊,排行榜有一个前三名,可能前15分钟这三个人是前三名,也许下一个15分钟又是别人前三名了,产品要求,这些人中只要是前三名的都要发奖品,思考了好久,最终决定用memcache来保存每15分钟的榜单前三名的信息。代码如下:

复制代码 代码如下:

public function getChargeRank3()
{
        $startime='2014-04-10 00:00:00';
        $endtime='2014-04-30 23:59:59';
        $sql="select top 3 user_id, sum (point) as total from  table where state=5 and cp_id>=11 and cp_id='$startime' and pay_time group by user_id order by total desc";
        $result=  Yii::app()->controller>createCommand($sql)->queryAll();
        $cache = yii::app()->cache->get($key);
        if($cache!=false)
        {
            foreach ($result as $key=>$val)
            {
  //这里为内部赠送礼物代码,,不便透漏
            }
        }
        YII::app()->cache->set($key, $result, strtotime($endtime));//把前三名写入缓存
}

希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
