I have the a day of the week saved as a number N for the customer in the database. e.g. Sunday = 0, Monday = 1, Tuesday = 2 etc.
I would like to have a statement that can tell if it's 2 days before that day.
For instance if…
customer day = 0 and today is 5 = true
customer day = 5 and today is 3 = true
customer day = 1 and today is 6 = true
if(($today+2)%7 == $customer)//ok
