Question

我的mysql有一个小问题。我有一套日期范围。例如：从2011年1月1日至2011年6月1日开始，此范围的价格为每天4500美元。下一个日期范围从01-07-2001开始到2011年12月1日，此范围的价格为：每天300美元

如果某人在ex：05-04-2011和10-07-2011之间注册了一天，我需要添加天数的价格。在这两个日期范围之间，价格是不同的。如何单独添加

这是ma tbl

谢谢

Answer 1

你可以制作一个循环...

并且每次增加日期然后进行查询以知道此日期值落在哪个col中..并且因此您可以获得相应的数量..

为此您需要管理日期，例如每月有多少天......如果年份发生变化，那么您还需要将月份设置为1 ..

我已经制作了一个代码......来显示日历。你可以适当地使用chages吗

$date_array = array();
$date_array = explode('-',$end_date);
