我两张表
表a        id  姓名  班级编号
表b         班级编号   班级中文名称

在php中，我想要这样显示

软件班
  张三李四 .....

绘画班

   王五 ........

请问在php中怎么体现啊，另外我是用的smarty。

回复讨论(解决方案)

没用过smarty，直接sql语句查出来，按照你期望的方式显示出来不行吗。

select a.班级编号,b.班级中文名称 , group_concat(a.姓名) as name_group from 表a a left join 表b b on a.班级编号=b.班级编号 group by a.班级编号

这样查询出来了就容易了

select a.班级编号,b.班级中文名称 , group_concat(a.姓名) as name_group from 表a a left join 表b b on a.班级编号=b.班级编号 group by a.班级编号

这样查询出来了就容易了

不好意思，我的意思是php能返回一个二维数组
