PHP Bug Type: Arrays related
Bug description: foreach (var as &var construct overwrites last element of
array
Description:
------------
it looks like foreach (var as &val) syntax leaves a refecence alive after
the last iteration. calling a subsequent foreach (var as val) (same
variable being used to iterate, but not as a ref now), the reference from
the first foreach is used to update the array...
Reproduce code:
---------------
<?php
$array = array(1, 2, 3);
foreach ($array as &$a) {
}
unset($a);
var_dump($array);
foreach ($array as $a) {
}
var_dump($array);
Expected result:
----------------
$array unchanged
Actual result:
--------------
$array changed.
