Edit report at https://bugs.php.net/bug.php?id=60302&edit=1 ID: 60302 Comment by: seld@php.net Reported by: kontakt at beberlei dot de Summary: DateTime::createFromFormat should new static(), not new self() Status: Assigned Type: Feature/Change Request Package: Date/time related PHP Version: Irrelevant Assigned To: derick Block user comment: N Private report: N New Comment: I added this in my subclass. Works well as a workaround, but it would be nice to have it in code indeed. public static function createFromFormat($a, $b, $c = null) { $date = $c ? parent::createFromFormat($a, $b, $c) : parent::createFromFormat($a, $b); return new static('@'.$date->format('U'), $date->getTimeZone()); } Previous Comments: ------------------------------------------------------------------------ [2011-11-14 21:51:54] derick@php.net Had a quick look at this, but it wasn't as simple as I thought. Needs some more investigation. ------------------------------------------------------------------------ [2011-11-14 20:00:54] kontakt at beberlei dot de Description: ------------ I want to extend DateTime, but without DateTime::createFromFormat, actually creating instances from my class, i.e. "MyDateTime::createFromFormat" this is rather problematic. Test script: --------------- <?php class MyDateTime extends DateTime { } $d = MyDateTime::createFromFormat('Y-m-d', '2011-01-01'); echo get_class($d); Expected result: ---------------- MyDateTime Actual result: -------------- DateTime ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=60302&edit=1
