Edit report at https://bugs.php.net/bug.php?id=77903&edit=1 ID: 77903 User updated by: gituser at yandex dot com Reported by: gituser at yandex dot com Summary: ArrayIterator stops iterating after offsetSet call Status: Open Type: Bug -Package: SPL_Types +Package: SPL related Operating System: Ubuntu 18.10 (64-bit) PHP Version: 7.3.4 Block user comment: N Private report: N New Comment: Hmm... Looks like SPL_Types https://www.php.net/manual/en/book.spl-types.php which hasn't been updated for more than 5 years, isn't the same as SPL https://www.php.net/manual/en/book.spl.php I think I found the correct category now.
