Bug description: Array sequence corrupted when elements are added with double digit indexes

Description:
------------
When I create an array using the following code the array is corrupted for
some reason, as if the double digits were misinterpreted or misread at some
point. From my experience it happens specifically on index 08 and 09 (which
are set to 0) Even if the order is different.
The consequence is that data with index 08 will be overwritten by 09 or 09
will be overwritten by 08 if 08 is set after 09.

Example code:




Reproduce code:
---------------
$list = array();
$list[01]='a';
$list[02]='b';
$list[03]='c';
$list[04]='d';
$list[05]='da';
$list[06]='db';
$list[07]='dc';
$list[08]='e';
$list[09]='ea';
$list[10]='eb';
$list[11]='ec';
$list[12]='f';

echo '<pre>';
var_dump($list);
echo '</pre>';

Expected result:
----------------
array(11) {
[1]=>
string(1) "a"
[2]=>
string(1) "b"
[3]=>
string(1) "c"
[4]=>
string(1) "d"
[5]=>
string(2) "da"
[6]=>
string(2) "db"
[7]=>
string(2) "dc"
[8]=>
string(2) "e"
[9]=>
string(2) "ea"
[10]=>
string(2) "eb"
[11]=>
string(2) "ec"
[12]=>
string(1) "f"
}

Actual result:
--------------
array(11) {
[1]=>
string(1) "a"
[2]=>
string(1) "b"
[3]=>
string(1) "c"
[4]=>
string(1) "d"
[5]=>
string(2) "da"
[6]=>
string(2) "db"
[7]=>
string(2) "dc"
[0]=>
string(2) "ea" //<- Here 09 overwrote 08 which was also set to 0 by the
parser/interpreter?
[10]=>
string(2) "eb"
[11]=>
string(2) "ec"
[12]=>
string(1) "f"
}

New Comment:

Sorry, but your problem does not imply a bug in PHP itself. For a
list of more appropriate places to ask for help using PHP, please
visit [url]http://www.php.net/support.php[/url] as this bug system is not the
appropriate forum for asking support questions. Due to the volume
of reports we can not explain in detail here why your report is not
a bug. The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.
