Bug description:Foreach not running through added elements when passed by
reference
Description:
------------
I found out that foreach sometimes doesn't run through elements added to an
array
when the value is passed by reference. I haven't tested enough to say it
for sure,
but I think it happens only on elements added on what would be the last
iteration
of foreach.
Test script:
---------------
$array = array('a', 'b', 'c');
foreach ($array as $i => &$val) {
echo $val.' ';
if ($i % 2 == 1) $array[] = $val.'2';
}
Expected result:
----------------
When it reaches $array[1] (b), it creates $array[3] with the value "b2".
Then it
runs through $array[3] and creates $array[4] with the value "b22". After
that, it
should run through $array[4] too, outputting altogether "a b c b2 b22" and
stopping.
Actual result:
--------------
Since at the start of the iteration, $array[3] is the last element of the
array,
after $array[4] is created in that iteration, it doesn't run through it,
outputting just "a b c b2". Still, $array[4] is created.
