Bug->Req #64399 [Opn->Wfx]: ArrayObject works with ArrayObject as input but not ArrayAccess

Edit report at https://bugs.php.net/bug.php?id=64399&edit=1 ID: 64399 Updated by: nikic@php.net Reported by: kotlyar dot maksim at gmail dot com Summary: ArrayObject works with ArrayObject as input but not ArrayAccess -Status: Open +Status: Wont fix -Type: Bug +Type: Feature/Change Request Package: SPL related PHP Version: Irrelevant Block user comment: N Private report: N New Comment: If you pass an object to ArrayObject (and it is not an ArrayObject or ArrayIterator itself), ArrayObject will work on the properties of the object. We cannot reasonably support ArrayAccess objects, because ArrayObject requires more than this interface to provide its functionality. In particular, it would also need at least Traversable and Countable. However, even with all of these we still couldn't provide complete functionality: The sorting methods essentially require random-access iterators, a concept that doesn't even exist in PHP.

But it is not true. Test script: --------------- https://gist.github.com/makasim/5123486 Expected result: ---------------- either YourCustomArrayObject::offsetExists or YourCustomArrayObject::offsetGet is called It should output 1 or 2 and exit the script Actual result: -------------- PHP Notice: Undefined index: whatever in /home/maksim/test.php on line 57 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=64399&edit=1
