Adding to dates

[furious5]

Ran in to a bit of a problem when adding a date.

Basically I can get the code to add the selected number of days, however it remains within the same year.

I guess this is because I am using the date() function, any suggestions how to overcome this?

$date_test = date('d-m-y', strtotime("$date + $day_calculate[$days]"));

Dates are a pain to work with because they are not real numbers. You can't just add x days to $date, you need to convert to timestamps or something before doing that. What format are $date and $day_calculate[$days] in?

Tell me about it, and I thought I had dates sussed!

$date = "03-01-04";

$date_temp = "18-01-03";

Therefore they are in the correct format, my problem is with using the date() function.

If you use timestamps except when outputting the date, you'll find it much easier.

As said above, convert your dates to timestamps using mktime() or gmmktime() before using the date() function. Then all you have to worry about is leap years and daylight savings time 😉

Best thing I can say is find a date manipulation class on teh Interweb, theres lots about 🙂

One thing about timestamps, they are only accurate from 1970 to about 2037 (I think)
