Bug description: foreach nullifies index of an inexed array
Description:
------------
When I use foreach($array as $key => $value) on an indexed array,
afterwards the index value, when viewed with key($array) is null instead
of an integer. This means that when my code tests the array to see if it
is either indexed or associative it is given the wrong answer.
Reproduce code:
---------------
<?php
$array[] = 'string of data';
if (is_int(key($array))) {
echo "array is indexed\n";
} else {
echo "array is associativ\/n";
} // if
foreach ($array as $key => $value) {
if ($key === key($array)) {
echo "they are the same\n";
} else {
echo "they are NOT the same\n";
} // if
} // foreach
if (is_int(key($array))) {
echo "array is indexed\n";
} else {
echo "array is associative\n";
} // if
?>
Expected result:
----------------
The output 'array is indexed' should be produced both before and after the
foreach() statement.
Actual result:
--------------
The key of an indexed array, when viewed with key($array), is not being
reported as an integer.
