Question

我正在为学校做时间表。我已经从数据库中选择了数据，但所有数据都在开始时 - 上午7点10分（图1）显示。但是一些课程从7,10开始，其他课程从早上8点开始。如果课程从早上8点开始，我不知道这些数据如何变化。我发现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（图片的顶行），我需要移动数据 pict 1

我用foreach循环做了它，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; 分开的课程意味着学生在一个课时有2个不同的课程; $q是分课的索引; listofhours是07：10,08：00,08：50等。
