calculating date 6 months ahead...

No luck yet!

I'm trying to calculate the date 6 months from today, but I can't seem to get it exactly!

This is what I'm doing:

1) Getting user input for MONTH, DAY, and YEAR (not necessarily in this order).

This is what I'm still trying to do:

2) Add 6 and 12 months to the date received by the user.

Anyone has any idea how I would go about doing this in PHP?

Thanks in advance,
Ilir.

Well, after you get today's month, you can add 6 to it. Then check if the resultant month is greater than 12. If it is, then subtract 12 to the month and add 1 to the year. If it's not greater than 12, then it's fine.

$date = date('Y m d',mktime(0,0,0,$month+6,$day,$year));

list($year,$month,$day) = explode(' ',$date);

2002-17-10 is correctly interpreted as 2003-05-10.

...A problem with doing it this way though, is that if today's date is May 31, then by following my algorithm, you'd get November 31, which is an invalid date, so you'd have to check for that kind of stuff...problems will also arise with February.

Another algorithm would be to use timestamps, and then add the number of seconds that 6 months would be. The slight problem with this, is that all the months will be either 30 or 31 days, so the resultant month will be slightly off.

Hm. I'm actually quite chuffed by this:

$date = date('Y m d',mktime(0,0,0,11,31,2002));

I'm gonna have to look at the source code.
