php如何把一个消息发送给多个用户。
比如我现在有user表,里面有id,users,pwd,yonghuzu
里面有三条记录users有
admin 管理员组(yonghuzu)
张三 vip高级用户(yonghuzu)
李四 vip高级用户(yonghuzu)
另外一个页面,我想实现这样子的结果。。
比如我有发送一句话给一个或者多个用户、用户组,如何发送。如何设计表才比较合理的存储数据并方便读取。。
我是打算设计id(自动编号),cont(发送的内容),username(发送的单个用户)
这样子发送给单用户,就很方便,
但是这样子如何是发送给多个用户,和用户组的话,就不知道username或者后面的怎么读取比较合理了。
还要考虑到,用户登陆后,然后方便去读取关于这个用户的消息列表页面。
回复讨论(解决方案)
可以考虑下分三张表
1.用户分组
2.用户表
3.发送给用户的消息表
其中用户表需要有个字段和用户分组的关联,消息表有个字段存用户id号 和用户表关联。
mysql update
1 你好 1,2,4,5
2 他好 3,4,5
3 我们都好 1,2
4 哈哈 2,3,4
后面的数组的是用户。
第一个是自动编号id,第二个cont内容,第三个是用户
现在我要出去用户ID为4的所有消息。。怎么才能出去到呢
如果你表是象你说的那样设计就没办法直接用sql语句去取出数据了,
可以考虑下每天信息都存一条记录,比如:4 哈哈 4
这样查询起来就比较容易了。
