Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php The end date is not supposed to be modifiable. ------------------------------------------------------------------------ [2018-07-13 14:20:41] jerry at jmweb dot net Description: ------------ When DatePeriod is instantiated with DateTime objects (as opposed to DateTimeImmutable objects), the getEndDate() instance method does not return a reference to the object's internal end date DateTime object. Test script: --------------- $period = new DatePeriod( new DateTime( '2018-01-01' ), new DateInterval( 'P1D' ), new DateTime( '2018-01-02' ) ); var_dump( $period->getEndDate()->add( new DateInterval( 'P1D' ) ) === $period->getEndDate() ); Expected result: ---------------- bool(true) Actual result: -------------- bool(false) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76620&edit=1
