So for goodness' sake just choose a sensible value to limit the loop -- I was just taking a stab in the dark from your mention of max 31 days' difference to guess it was a day-number within a month, and hence my assumption that only +ve values would be valid. You really haven't given us very much to go on here -- it might be easier to suggest a solution if you told us more about what *exactly* it is you're trying to do. And a little bit more of your *actual* code (not "something like") might help things along, too. > > "Mike Ford" <[EMAIL PROTECTED]> wrote in message > news:[EMAIL PROTECTED] >> On 10 September 2003 11:26, zavaboy contributed these pearls >> of wisdom: >> >>> // Ok, I have a loop: >>> for ($i = $Date; $i >= $sDate; $i--) >>> >>> // Somthing like this is inside the loop: >>> if ($Exists) >>> echo "Something here."; >>> else >>> $sDate--; >>> >>> I have it check if it exists, if it doesn't, then it reduces >>> $sDate by 1. $sDate is initially 3 to 31 days less than >>> $Date.
