php - 选择与某个日期重叠的日期范围

Question

可以说这是我的桌子，如下所示。

ID | Startdate           | Enddate
-----------------------------------------------
1  | 2012-12-12 08:00:00 | 2012-12-15 18:30:00
-----------------------------------------------
2  | 2012-12-11 00:00:00 | 2012-12-16 00:00:00
-----------------------------------------------
3  | 2012-12-16 08:00:00 | 2012-12-17 18:30:00
-----------------------------------------------
4  | 2012-12-13 00:00:00 | 2012-12-14 11:30:00
-----------------------------------------------

选定的日期范围是 Id 1, 2012-12-12 08:00:00 到 2012-12-15 18:30:00 。我想选择跨越日期范围的任何日期。

正确的 Id 将是 2 和 4 。希望大家理解，有什么问题欢迎追问。谢谢你。
