From: Evgeny dot Mazanik at gmail dot com
Operating system: Windows 10
PHP version: 7.2.6
Package: SPL related
Bug Type: Documentation Problem
Bug description:Different behavior between Array and ArrayIterator in foreach loop...
Description:
------------
---
From manual page: http://www.php.net/arrayiterator.offsetunset
---
Different behavior when using Array and ArrayIterator in a foreach loop
when using unset () for an associative array.
1. When using an Array in a loop and removing an element in the body of
the loop, the loop is executed across all elements of the array.
2. When using ArrayIterator in a loop and deleting an element in the
body of the loop, the loop is NOT performed on all elements of the
array.
PS:
A similar problem:

Test script:
---------------
http://sandbox.onlinephpfunctions.com/code/ff65bf3858b153780b588476ebaa77b0aba7b4db
Actual also for PHP 7.2.4, 7.2.6
Expected result:
----------------
Probably:
Via array:
item1
item2
item3
Via ArrayIterator:
item1
item2
item3
Actual result:
--------------
Via array:
item1
item2
item3
Via ArrayIterator:
item1
item3
