Description:
------------
Hi there!

I am having a standard class using numeric keys as properties which works fine in general. The numeric keys are currently Strings. After serializing and unserializing the class, the properties will be converted to Integers which makes them unaccessible. Have a look at the code example below.

Regards
Lukas

Test script:
---------------
<?php

$a = new stdClass();
$a->{0} = 'X';
$a->{1} = 'Y';

var_dump($a);
echo "\n0:", $a->{0}, "\n1:", $a->{1}, "\n\n";

$b = unserialize(serialize($a));

var_dump($b);
echo "\n0:", $b->{0}, "\n1:", $b->{1}, "\n\n";

?>

Expected result:
----------------
object(stdClass)#2 (2) {
  ["0"]=>
  string(1) "X"
  ["1"]=>
  string(1) "Y"
}

Actual result:
--------------
object(stdClass)#2 (2) {
  [0]=>
  string(1) "X"
  [1]=>
  string(1) "Y"
}
