#47846 [Fbk]: Error in DateTime class when initialising with '2009-02'

ID: 47846 Updated by: rasmus@php.net Reported By: brooksie155 at yahoo dot com Status: Feedback Bug Type: Date/time related Operating System: CentOS PHP Version: 5.2CVS-2009-03-31 (snap) New Comment: The output from your script on my box: America/Los_Angeles array(12) { ["year"]=> int(2009) ["month"]=> int(2) ["day"]=> bool(false) ["hour"]=> bool(false) ["minute"]=> bool(false) ["second"]=> bool(false) ["fraction"]=> bool(false) ["warning_count"]=> int(0) ["warnings"]=> array(0) { } ["error_count"]=> int(0) ["errors"]=> array(0) { } ["is_localtime"]=> bool(false) } 2009-03-03T00:00:00-0800 That 'false' there on the date will make it default to today's date. Seeing it on both 5.2 and 5.3 on Freebsd. Previous Comments: ------------------------------------------------------------------------ [2009-03-31 09:01:28] derick@php.net Just as a comment to Rasmus, that's not true. The format "2009-02" implicitly sets the day nr as 1. ------------------------------------------------------------------------ [2009-03-31 08:56:25] derick@php.net I can not reproduce this, what does the following output: <?php $str = "2009-02"; echo date_default_timezone_get(), "\n"; var_dump( date_parse( $str ) ); $date = new DateTime( $str ); echo $date->format( DateTime::ISO8601 ), "\n"; ?> ------------------------------------------------------------------------ [2009-03-31 08:56:02] rasmus@php.net Not a bug. As documented, this defaults to now and you can override individual components in the constructor. In your case you have chosen Feb. 2009, but didn't specify a day of the month. PHP picks todays day, which is the 31st day of the month. The 31st day of Feb will fall in March since Feb doesn't have 31 days. ------------------------------------------------------------------------ [2009-03-31 08:44:45] brooksie155 at yahoo dot com Description: ------------ There is a bug in the constructor of this object if you are only specifying the month and the year when dealing with the month of February. Reproduce code: --------------- $date = new DateTime('2009-02'); echo $date->format('Y-m'); Expected result: ---------------- 2009-02 Actual result: -------------- 2009-03 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=47846&edit=1
