php日历签到该怎么做?
嗯,这个,我以前遇到过。
签到表会非常庞大。
假如一个月30天,10个用户,那么就得有300条记录。
数据交互,自然就是ajax了。
另一种存储方式,就是扔到mongodb。
新建一张签到表,存放签到日期等信息,然后监听你日历的每一天的click事件,通过ajax提交一下不就可以了吗(存的时候使用服务器端时间)
<code>可以用redis来存,每一个月建一个key:value的键值对, 比如第一个月就用sign:111:1,分别表示用户id和签到月份, 然后value用队列,将每次签到的数据尾插到队列末尾, 每次需要显示签到表的时候去查询这个本月的key就可以了。 </code>
初始化日历的时候,判断一下当天是否已经签到(日历的当天对比数据库中的数据),假设当天签到,add Class用来表示已经签到了!否则继续。 你初始化日历的时候是怎么做的,那或许可以贴上来。

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.

The steps to build an efficient shopping cart system using sessions include: 1) Understand the definition and function of the session. The session is a server-side storage mechanism used to maintain user status across requests; 2) Implement basic session management, such as adding products to the shopping cart; 3) Expand to advanced usage, supporting product quantity management and deletion; 4) Optimize performance and security, by persisting session data and using secure session identifiers.
