ID: 26565 Comment by: fortizma at gmail dot com Reported by: michaelw at darkhorse dot com Summary: strtotime('this month') resolving to the wrong month? Status: Closed Type: Bug Package: Date/time related Operating System: Mac OS X 10.2.x PHP Version: 4.3.4 Assigned To: derick Block user comment: N Private report: N New Comment: Ok Rasmus thanks for your reply. However in my opinion is not a correct behavioural. So if I ask today march, 30 for the "last month" the function should return feb 28. The function should not assumes that I meant 2 days after Feb.28, when I'm just passing as param lastmonth. Anyways, in my opinión the function is not working properly, because if I'm asking about lastmonth the answer should not be the current month. how you can create a function working properly, that return the correct last month every day in PHP 5.2.x. Previous Comments: ------------------------------------------------------------------------ [2011-03-30 22:39:23] ras...@php.net To the people adding comments about +-1 month here. This really isn't a bug. Read the link Derick provided: http://derickrethans.nl/obtaining-the-next-month-in-php.html It doesn't matter if you are going ahead 1 month or back 1 month. The logic is the same. It tries to find Feb.30 which doesn't exist, so instead of walking backwards to Feb.28 it assumes you meant 2 days after Feb.28 which is obviously in March. Like I said in the comments at that link, for better or worse, this is the UNIX convention for time manipulation. Most UNIX tools will behave exactly like this. In order to do this correctly, you should be specifying a day in the month as Derick suggests in that post. ------------------------------------------------------------------------ [2011-03-30 22:01:12] rbredlau at broadlux dot com I am having the exact same error as fortizma. <?php $runtm = time(); $month = strtotime( '-1 month', $runtm ); $ts = date( 'n/j/Y g:i a', $runtm ); $ts2 = date( 'n/j/Y g:i a', $month ); $last = date( 'Y-m-F', $month ); echo $ts .

Do this occur due to 2011 is not a leap year? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
