如何在数组php中移动元素

I´m doing timetable for school. I already have selected data from DB, but all data are represented at the beginning-at 7,10am(pict 1). But some lesson starts at 7,10, others starts at 8am. I have no idea how these data shift if the lessons starts f.e at 8am. I found php function array_unshift, but actually do I need add some elements on the beginning? I need to shift the data if the start_time of the lessons is not equal to start_time(top row on the picture) pict 1

I did it with foreach loop and the array which represent timetable is: $timetable[$day]['lessons'][$z]['dividedlessons'][$q]['start_time']

$z is index for individual lesson - on the pic 0,1,2,3,4; divided lessons mean when students have 2 different lesson in one lesson hour; and $q is index for divided lesson; listofhours is 07:10, 08:00, 08:50,etc.
