简介

DateTimeInterface is meant so that both DateTime and DateTimeImmutable can be type hinted for. It is not possible to implement this interface with userland classes.

版本	说明
5.5.8	Trying to implement DateTimeInterface raises a fatal error now. Formerly implementing the interface didn't raise an error, but the behavior was erroneous.

DateTime::diff — Returns the difference between two DateTime objects
DateTime::format — Returns date formatted according to given format
DateTime::getOffset — Returns the timezone offset
DateTime::getTimestamp — Gets the Unix timestamp
DateTime::getTimezone — Return time zone relative to given DateTime
DateTime::__wakeup — The __wakeup handler
