我正在做学校的时间表。我已经从 DB 中选择了数据，但所有数据都在早上 7,10 开始表示（图 1）。但是有些课从 7,10 开始，有些课从早上 8 点开始。如果课程在上午 8 点开始，我不知道这些数据如何变化。我找到了php函数array_unshift，但实际上我需要在开头添加一些元素吗？如果课程的 start_time 不等于 start_time（图片顶行） pict 1 ，我需要移动数据

我用foreach循环做到了，代表时间表的数组是： $timetable[$day]['lessons'][$z]['dividedlessons'][$q]['start_time']

$z是个别课程的索引 - 在图片 0、1、2、3、4 上；分课是指学生在一课时有两节不同的课；$q是分课的索引；listofhours 是 07:10、08:00、08:50 等。

“skratka”是天的缩写；'hodiny' 是课程，'delenehodiny' 是分开的课程。
