I have 2 dates in Laravel, how can I run a auto generate post to go through between two dates with time period?

I want to create a Question (question table) that has startDate and endDate and period that is in hour (1-2-3-... hours) and user_id

Now I want to auto generate question rows in another table (Question_user) between two dates with period

ex:

startDate = 2019-11-01 00:00:00

endDate = 2019-11-20 12:00:00

period = 12

Now I want to create questions in (Question_user) at:

2019-11-01 00:00:00

2019-11-01 12:00:00

2019-11-02 00:00:00

...

How can I do this?

*Date format -->Year/Month/Day
