Edit report at http://bugs.php.net/bug.php?id=52015&edit=1 ID: 52015 Patch added by: degeberg@php.net Reported by: ko dot fivestar at gmail dot com Summary: Ending date is ignored while iterating DatePeriod Status: Open Type: Bug Package: Date/time related Operating System: Ubuntu 10.04 PHP Version: 5.3.2 New Comment: The following patch has been added/updated: Patch Name: php_bug52015.diff Revision: 1275919428 URL: http://bugs.php.net/patch-display.php?bug=52015&patch=php_bug52015.diff&revision=1275919428 Previous Comments: ------------------------------------------------------------------------ [2010-06-07 16:03:44] degeberg@php.net Whether or not it's a bug is debatable. It could be considered a half-open interval (which would then make it a documentation issue). Changing it to a closed interval would break backwards compatibility. It would probably be better adding one more option to DatePeriod that allows the inclusion of the end date. The attached patch implements that. ------------------------------------------------------------------------ [2010-06-07 13:56:17] ko dot fivestar at gmail dot com Description: ------------ When passing DateTime objects to first and third argument of DatePeriod constructor, the specified date on the third argument is not being interated when both DateTime object contains same time value. After looking through ext/date/php_date.c, date_period_it_has_more() function (line 1831) had following code: --------------- return object->start->sse < object->end->sse ? SUCCESS : FAILURE; --------------- While the operator "<" is currently used to compare values, operator "<=" is more appropriate for this content. Test script: --------------- $period = new \DatePeriod( new \DateTime('2010-06-01'), new \DateInterval('P1D'), new \DateTime('2010-06-03') ); foreach ($period as $day) { echo $day->format('Y-m-d') . "\n"; } Expected result: ---------------- 2010-06-01 2010-06-02 2010-06-03 Actual result: -------------- 2010-06-01 2010-06-02 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52015&edit=1
