UBB.Developers Forums UBB.threads 7 Development How Do I? Okay Brainiacs..

Got a question I know I am missing it.. I need a formula for this

I have 7 items and there are 31 days and I would like to use each item once a day and then go back to the beginning on day 8 and then use items again and over and over until day 31.. whats the formula. you can use x and y or write it up in php I don;t care I just need the formula

Are you looking for a one line formula, or a code snippet/loop?

I thought this would be a fun question to throw around my IT department here at work, here are the responses so far.

1. From our scripting guy, mostly KIX:

Assuming $i is Day of week.

FOR $i = 0 to 6

IF item.date < 31 THEN

-- Use item

-- move to “example”

END IF
NEXT

2. From our DB guy:

31days divided by 7items = number of times items can be reused.

I came up with.

$daysinmonth=date('t',time());
$ammountofcomics = count($local_files)-1;
for($rotatecomics = 0; $rotatecomics <= $daysinmonth; $rotatecomics++)
{
$random_comic_array[]=($rotatecomics % $ammountofcomics)+1;
}

$dayofweek=date('j',time());
$random_comic = $random_comic_array[$dayofweek];
$comics_image_name = $local_files[$random_comic];
$local_img_url = "{$comics_config['main_comics_url']}comics/";
$frontpage_comic = $local_img_url . $comics_image_name;

I don't think I understand this...
You want to get the item given the day #?

so
1 -> item 1
2 -> item 2
7 -> item 7
8 -> item 1
Is that what you want?

Just go:

Day -> item (Day % 7)+1

yeah I have a varrying ammount of items and a fixed number of days per month and needed the calculation.
