Re: getting a string result from Date

Hi Lorenzo Thanks for the big explanation - I was sure I passed the invalid date into Date and got valid results, but now I can see this does in fact fail. I think I mixed it up with dates fed into mysql (date columns) which work in both scenarios WHERE day > '2003-9-04' and WHERE day > '2003-09-04' cheers Demian Lorenzo Alberton wrote:

Hi Lorenzo please give the code a try, i was baffled to find the second $currdate assignment doesn't work when it's fed back into the argument of the Date object in the next iteration of the loop.

sorry, I had only looked at the first run, didn't notice $currDate was fed back in the loop. Anyway, PEAR::Date constructor accepts one of the following standards: DATE_FORMAT_ISO, ISO_BASIC, ISO_EXTENDED, TIMESTAMP, UNIXTIME. your first assignment ($currDate = "2003-9-04";) is invalid, so by default $date->year is set to 0, $date->day=1, $date->month=1. When you call subtractSpan(), though, Date_Calc::dateToDays() is internally called, and that method supposes the passed date is in the ISO format, without any check. In this method, the 0-1-1 date is somewhat changed into the date of the current day. Since in the loop you keep on passing an invalid date to Date() constructor, the same sequence described above happens at each iteration. Wrapping up... I don't think it's a bug in Date(), (even if I agree a better check in dateToDays() wouldn't hurt), because the input is not valid (at least according to Date capabilities), so you can't expect a valid output ;-) HTH Lorenzo
