“抢座位”的逻辑问题:如何获得可帮和可拆的部分
$seat_parts = array('凳腿', '凳腿', '凳腿', '凳腿', '椅背', '扶手', '扶手');
数据库中
<code>seat_build 记录用户椅子的进度 user_id total_step(完成椅子需要的步数) done_step(已经完成的步数/部分) seat_build_record 表用来记录相关的帮和拆记录 user_id to_user_id(关联seat_build中的user_id) part_id(对应$seat_parts中的索引) type(-1表示拆 1表示帮忙) </code>
规则:
<code>座椅完成以后就不能在拆了 拆的部分职能是在已经完成的部分中选 </code>
问题:
<code>对于seat_build中的某个用户来说,如何快速的获得帮和拆的相应的座椅部分的索引?思路或者具体的代码均可</code>
