Edit report at https://bugs.php.net/bug.php?id=79228&edit=1 ID: 79228 Updated by: derick@php.net Reported by: eric at ericstern dot com Summary: Allow DateTimeInterface to be implemented in userland -Status: Open +Status: Wont fix Type: Feature/Change Request Package: Date/time related PHP Version: Irrelevant Block user comment: N Private report: N New Comment: This can not be done, as the DateTime extension requires internal information to be present for classes that implement DateTimeInterface, and this internal (C-based) information can not be provided by user-land. Previous Comments: ------------------------------------------------------------------------ [2020-02-05 01:21:06] requinix@php.net Happened during bug #65768 "because ext/date relies on classes implementing it to support certain internal structures". https://git.php.net/?p=php-src.git;a=commit;h=5f09944662e09ea0b3f93cfab8702f188955e68c ------------------------------------------------------------------------ [2020-02-05 00:59:46] eric at ericstern dot com Description: ------------ Since DateTimeInterface has a restriction that it cannot be implemented in user space, certain operations (especially in testing) become unnecessarily difficult. It would be great if a future version of PHP lifted this restriction.
