ID: 52798 Updated by: s...@php.net Reported by: ebinachon at pierre-vacances dot fr Summary: dateTime => function diff => days KO -Status: Verified +Status: Feedback Type: Bug Package: Date/time related Operating System: windows xp PHP Version: 5.3.3 Assigned To: derick Block user comment: N Private report: N New Comment: Please try using this snapshot: http://snaps.php.net/php5.3-latest.tar.gz For Windows: http://windows.php.net/snapshots/ Works fine for me with current SVN 5.3 HEAD. Previous Comments: ------------------------------------------------------------------------ [2010-09-08 18:12:46] cataphr...@php.net The problem was the call to floor(). The compiler gave a warning: "d:\users\cataphract\documents\php-trunk\ext\date\lib\interval.c(57) : warning C4013: 'floor' undefined; assuming extern returning int" The assumption is wrong, because it calls double __cdecl floor(_In_ double _X); Which takes and returns a larger type. I removed the call to floor, which is unnecessary since it's an integer division. I also changed the call to abs to a call to llabs to avoid the conversion from long long to int and then to long long again. ------------------------------------------------------------------------ [2010-09-08 18:03:46] cataphr...@php.net The following patch has been added/updated: Patch Name: date_diff Revision: 1283961826 URL: http://bugs.php.net/patch-display.php?bug=52798&patch=date_diff&revision=1283961826 ------------------------------------------------------------------------ [2010-09-08 17:36:02] cataphr...@php.net I can reproduce only on Windows. The exactly value varies (seems to be garbage memory). ------------------------------------------------------------------------ [2010-09-08 17:19:52] ebinachon at pierre-vacances dot fr Description: ------------ I have a probleme with the function diff of dateTime. When i do a test, the "days" result is always : 6015. All the other informations ( Y, m, d, ... ) are correct. Have-you an idea ? Test script: --------------- Exemple : $date1 = new DateTime('2010-01-01'); $date2 = new DateTime('2010-03-13'); $interval = $date2->diff($date1); Zend_Debug::dump($interval); //OR Zend_Debug::dump($interval->format('%a')); ------------------ Result : object(DateInterval)#174 (8) { ["y"] => int(0) ["m"] => int(2) ["d"] => int(12) ["h"] => int(0) ["i"] => int(0) ["s"] => int(0) ["invert"] => int(0) ["days"] => int(6015) } Expected result: ---------------- days => 71 Actual result: -------------- days => 6015 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52798&edit=1
