Increment month in a "for" loop?

Trent_Hatred

Hey all,

I'm trying to increment the month within a for loop, eg:

for ($i=1; $i<=$numberOfPayments; $i=$i+1)
{

This is for a simple ammortization calendar which, right now, only displays a number for each monthly payment (ie. term of 60 months, it displays 1-60).

How would I go about turning the 1-60 into months starting from January? The payment dates aren't being pulled from a database, so it will always start from January.

Thanks much in advance,
B

echo date('F',mktime(0,0,0,$i,1,0));

should work

Try something along the lines of:

for ($i=1; $i<=$numberOfPayments; $i=$i++)
  {
   echo date ("M", mktime (0,0,0,$i,0,0));
  }

Oh, these are fun!

For testing, I whipped this up:

for($a = 0; $a < 60; $a++)
{
	echo $a . ' : ' . ($a % 12) . ' : ' .  date('M', strtotime(($a % 12) + 1 . '/1/2003')) . '<br>';
}  // end for($a = 0; $a < 60; $a++)

The guts of this is ($a % 12). Not sure if you're familiar with the mod "%" operator, but it takes and divides $a by 12 and returns the remainder. In doing so, you end up with numbers that are never above your mod value (or mod 12 in this case). So for what you're needing to do, this should work out.

The messy echo statement is there so you can see what $a looks like, $a % 12 looks like, and then the month value actually being applied.

Man, I'm slowing down! Two of you beat me to the reply... 🙂

I haven't tried the mktime trick in this case where the month is behind the expected range...

Hehe don't worry!
I had to put a note that I am not a moderator bot in my sig. I was quitequick replying a few months ago, when I hda nothing better to do then program, and was online 18 hrs/day ;-)

Hehe, they both work great guys, thanks.

I wasn't even thinking along those lines when I came across this issue...

P.S. thanks for the prompt responses, good to know there's folks like you that are willing to help a greenhorn like myself. :p
