请教下PHP操作数据库的写法上的小问题
问题在哪里呢？我只要在参数中给了$order值，就找不到记录
但是不给这个值 ，就能查到5条记录
我感觉是语法上有些问题，请记手指点一下，多谢了
回复讨论(解决方案)
order子句需要在limit子句前，而你的代码次序正好反了，所以导致语法错误。一般来说，limit是SQL语句中最后一个组成部分。
顺带提一下，你目前只是发现了查不到值，而这实际是SQL语句解析错误。如果你不知道怎么调试怎么发现问题，那么后面的路会很难走
$q = ' ORDER BY '.$order.' DESC ';
你这个方法只能对一个表使用吧。。这么多字段都写死了。。。
而且order by 位置写错了，先order by 然后 limit
