Bug description: incorrect processing of numerical string keys of array
(unserialize)
Description:
------------
php converts numerical string in array keys to integer if possible.
php4 converts those string while unserialize as well as while array
processing of php code
php5 converts those string while array processing of php code only, and
not converts while the unserialize a string
As the result - unserialized array can contains fake elements.
For example - there is no way to get access to the element by a key.
Reproduce code:
---------------
<?php
$a = unserialize('a:2:{s:2:"10";i:1;s:2:"01";i:2;}');
print $a['10']."\n";
$a['10'] = 3;
$a['01'] = 4;
print_r($a);
foreach ($a as $k => $v)
{
print 'KEY: ';
var_dump($k);
print 'VAL: ';
var_dump($v);
print "\n";
}
?>
Expected result:
----------------

(
[10] => 3
[01] => 4
