Edit report at https://bugs.php.net/bug.php?id=78181&edit=1 ID: 78181 Updated by: nikic@php.net Reported by: nyamsprod at gmail dot com Summary: DateInterval can no longer be comparable according to its public properties Status: Not a bug Type: Bug Package: Date/time related Operating System: No relevant PHP Version: 7.4.0alpha1 Block user comment: N Private report: N New Comment: This is already part of UPGRADING, see https://github.com/php/php-src/blob/PHP-7.4/UPGRADING#L50-L52. Previous Comments: ------------------------------------------------------------------------ [2019-06-19 11:37:57] nyamsprod at gmail dot com So this is a bug fix from all previous PHP versions maybe it should be added in the CHANGES files because the change in behaviour caught me off guard and I could not find any information in the documentation regarding upgrades or changes or fix. ------------------------------------------------------------------------ [2019-06-19 11:03:59] nikic@php.net DateInterval objects never compared according to their public properties -- they always compared equal. We may introduce comparable intervals (https://github.com/php/php-src/pull/4063), but they currently do not exist and have never existed. ------------------------------------------------------------------------ [2019-06-19 11:00:26] nyamsprod at gmail dot com Description: ------------ The DateInterval object exposes public properties. We should be able to compare two instances based on their public properties like it is possible for any other object. It is the case currently in PHP7.3- Test script: --------------- $interval1 = new DateInterval('PT3H'); $interval2 = new DateInterval('PT3H'); var_dump($interval1 == $interval2); var_dump($interval1 === $interval2); $obj1 = new stdClass(); $obj1->foo = 'bar'; $obj2 = new stdClass(); $obj2->foo = 'bar'; var_dump($obj1 == $obj2); var_dump($obj1 === $obj2); Expected result: ---------------- bool(true) bool(false) bool(true) bool(false) Actual result: -------------- Warning: Cannot compare DateInterval objects in /in/G7jM0 on line 6 bool(false) bool(false) bool(true) bool(false) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78181&edit=1
