$idss = '3,2,7,5';
$re = $db->findall('select id,title from aaa where id in('.$idss.')');
foreach($re as $list){
echo $list['id'].',';
}
输出结果是：2,3,5,7
怎么才能让它按照$idss的顺序输出：3,2,7,5, 呢？谢谢！
------解决思路----------------------
$re = $db->findall("select id,title from aaa where id in($idss) order by fiind_in_set(id, '$idsd')");------解决思路----------------------
$re = $db->findall("select id,title from table where find_in_set(id, ".$idss.")");
试试。
