Edit report at https://bugs.php.net/bug.php?id=63554&edit=1 ID: 63554 User updated by: francois dot gannaz at silecs dot info Reported by: francois dot gannaz at silecs dot info Summary: Is SplObjectStorage ordered? Status: Not a bug Type: Documentation Problem Package: SPL related PHP Version: Irrelevant Block user comment: N Private report: N New Comment: Thank you for your comment. Would it be possible to add this explanation to the documentation? Even one short sentence would be make it clearer that the map may not be iterable by insertion order. Previous Comments: ------------------------------------------------------------------------ [2013-01-12 05:00:31] frozenfire@php.net SplObjectStorage is implemented using an array as its internal storage mechanism, so one could consider it ordered. However, its purpose is more for to provide a mechanism whereby an object exist in the set or not, with no concerns for duplication in the set. I do not believe that the order of the set is relevant to its purpose. Its order in the set is determined entirely by the order in which the objects were attached. This is incidental, rather than intentional. ------------------------------------------------------------------------ [2012-11-18 20:19:48] francois dot gannaz at silecs dot info Description: ------------ The documentation describes SplObjectStorage as "a map from objects to data". Is this map ordered or not? As it seems to be ordered, at least with the PHP version I tested with, can we rely on this undocumented feature for future releases and different OS? Please detail this main characteristic. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=63554&edit=1
