Req #68061 [NEW]: DateTimeInterface::createFromInterface

From: evert at rooftopsolutions dot nl Operating system: Any PHP version: 5.6.0 Package: Date/time related Bug Type: Feature/Change Request Bug description:DateTimeInterface::createFromInterface Description: ------------ I am currently in the process of migrating my codebase to PHP 5.5 I do a lot of stuff with dates, so a big thing for me is to move everything to DateTimeImmutable. What this generally implies for me is: 1. I accept DateTimeInterface everywhere. 2. I emit DateTimeImmutable everywhere. Often times I will want to work internally with DateTimeImmutable. So I really need a way to 'cast' whatever I have to DateTimeImmutable. Unfortunately we only have: DateTimeImmutable::createFromMutable This means that I'll generally always have to check if I got a DateTime or DateTimeInterface, and only call createFromMutable _if_ it's a DateTime object. No huge deal, but it would be nicer if I can always call: DateTimeMutable::createFromInterface(DateTimeInterface $dt). But one step beyond that would be, and would be even more convenient, is if DateTimeInterface got a method : getImmutable() In the case of a DateTime we would get a Immutable copy of it, in the case of DateTimeImmutable, it can just return itself. -- Edit bug report at https://bugs.php.net/bug.php?id=68061&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=68061&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=68061&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=68061&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=68061&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=68061&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=68061&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=68061&r=needscript Try newer version: https://bugs.php.net/fix.php?id=68061&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=68061&r=support Expected behavior: https://bugs.php.net/fix.php?id=68061&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=68061&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=68061&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=68061&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=68061&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=68061&r=dst IIS Stability: https://bugs.php.net/fix.php?id=68061&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=68061&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=68061&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=68061&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=68061&r=mysqlcfg
