Bug #81427 [NEW]: Different behavior calling end() on an ArrayObject between 7.3.26 and 7.4.23
From: brian at deshong dot net
Operating system: Linux
PHP version: 7.4.23
Package: SPL related
Bug Type: Bug
Bug description:Different behavior calling end() on an ArrayObject between 7.3.26 and 7.4.23
Description:
------------
We've seen a variation in the behavior of end() when calling it on an
ArrayObject between 7.3.26 and 7.4.23.
The test script returns the final element in the ArrayObject on PHP
7.3.26, but false on PHP 7.4.23.
I'm unclear as to why this behavior has changed as there are no
documented changes to end() or ArrayObject behavior that I see in the
PHP 7.3 to 7.4 migration guide.
Test script:
---------------
<?php
$arrayObject = new ArrayObject();
$arrayObject->append(new stdClass());
$arrayObject->append(new stdClass());
var_dump(end($arrayObject));
Expected result:
----------------
I expect to have the final ArrayObject element returned by the call to
end() on both PHP 7.3.x and 7.4.x.
Actual result:
--------------
On PHP 7.3.26, the final object within the ArrayObject is returned.
On PHP 7.4.23, false is returned.
7.3.26
