我有两个表,表a是商品表,表b是留言表也就是用户对商品的评论,
a表 id(自增id) name(商品名称) money(商品价格) b表 id(自增id) content(留言内容) pid(对应的商品id) uid(用户id)
商品id 商品名称 商品价格 留言数量
xxx xxx xxx xxx
xxx xxx xxx xxx
要遍历出来且分页显示,主要是数据表之间怎么关联获取数据后再组成新的二维数组。
回复讨论(解决方案)
select a.id as aid,a.name as aname,a.money as amoney,b.id as bid from tableb as b left join table as a on b.pid=a.id where 条件 order by time desc limit 0,10 //每页10条,pageNow第几页
这样查出来的已经是二维数组了
select a.*,ifnull(b.c,0) from a left join (select pid,count(0)c from b group by pid)b on a.id = b.pid order by a.id desc limit 0,10;
谢谢,大家的热心解答

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
