How to send a range of dates to the database if I know the first and last?

Question

PHP

Hello. There is such a calendar https://jsfiddle.net/jw01gosb/47/. It is necessary that after selecting certain dates, they are recorded in the database, but it is necessary that all selected dates are recorded in the table. That is: if the interval from 01/01/16 to 01/04/16 is selected, then all numbers should be written to the table: 1, 2, 3 and 4 number. I can easily create rows with the last and first dates through php in the database, but I can’t, because each month has a different number of days, and what should I do, the range will be from 29.02.16 to 03.03.16 ? In my database, the string has the value text. Tell me how to send the entire range of dates to the database?

where selected_date between '2016-02-29' and '2016-03-16'

Answer 2

while + strtotime("+1 day", $timestamp): strtotime will correctly handle adding 1 day to the specified date, taking into account the length of the month, the change in the year, etc.
