PHP создает информацию о бронировании из массива с различными приоритетами и временными диапазонами на дату, которая не может перекрываться

Я сам разобрался с этой частью с помощью классов в php, возможно, я не был бы правильным способом сделать это. но по крайней мере он выводит то, что я хотел, вот что я сделал:

<?php
/*
This JSON encoded away contains the elements wich have been booked for each day, wich start and end time of the day
priority order is:
Normal: is the lowest priority
High: is always more important than normal
Superadmin: Is the highest priority and should always be shown over the other priorities
*/
$array =
