Question

I see there are other posts on this question in other languages, but I can’t find one for PHP. I’m not looking for the difference between two date times, but rather how many days different. For example:

2011-08-06 14:05:28

and

2011-08-07 08:46:28

are less then one day apart, but I want a function that will tell me they are on days that are one day apart, i.e. will return a value of 1 for these two dates, and return a value of 2 for the following dates, for example:

2011-08-06 23:05:28

and

2011-08-08 01:46:28

Really, I’m guessing it must be easy, but I’ve not worked much with dates before.

Oh, and one more constraint, I need something compatible with PHP 5.2, so can’t use DateTime::diff.

EDIT: changed to clarify that I do really need a numeric return value, sorry 🙂

Answer 1

if i interpret the question correctly, you need GregorianToJD or mysql to_days

Both functions return a julian day for a specific date, which is basically the number of days since “day 0”.
