查了一下资料You're probably trying to use an already used query, but I really don't have a clue because you were so kind to not provide any code or proper description at all.
PHP查询结果要把sql语句分成三部分，
①查询完sql语句后return $this->select($sql);
② 要抓取结果while($row=mysql_fetch_array($result))
③第三才是输出结果
我中间少了第二步 所有老是出现Warning: Invalid argument supplied for foreach() in
表面foreach的 options 不是个数组噢；
