Not gonna happen.

This IS definitely a bug. When I do foreach($Array AS $VAR) then it should return in var a NEW $VAR instance in any way, was it used previously or not. ------------------------------------------------------------------------ [2016-11-30 09:12:43] requinix@php.net Please take note of the big red warning in the documentation. http://php.net/manual/en/control-structures.foreach.php ------------------------------------------------------------------------ [2016-11-30 09:09:03] dorin dot marcoci at gmail dot com Description: ------------ Script below output A A instead of A B. Is this as designed? If I do unset($Item) before second foreach then it works as expected. Test script: --------------- <?php $Items = [['Code' => 'A'], ['Item' => 'B']]; foreach ($Items as &$Item) $Item['Hash'] = rand(1, 10); foreach ($Items as $Item) echo ' '.$Item['Code']; Expected result: ---------------- A B Actual result: -------------- A A ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=73622&edit=1
