Description:
------------
The same codes output the different results between ver5.3.8 & ver5.3.10:
<?php
$a = serialize((object)array(
’1′ => ‘aaa’,
’2′ => ‘bbb’,
’3′ => ‘ccc’,
));
$a = (array)unserialize($a);
$a[1] = ‘ddd’;
var_dump($a);
?>

// results before ver5.3.8：
array(3) {
[1]=>
string(3) “ddd”
[2]=>
string(3) “bbb”
[3]=>
string(3) “ccc”
}

// results in ver5.3.10：
array(4) {
["1"]=>
string(3) “aaa”
["2"]=>
string(3) “bbb”
["3"]=>
string(3) “ccc”
[1]=>
string(3) “ddd”
}

Test script:
---------------
<?php
$a = serialize((object)array(
’1′ => ‘aaa’,
’2′ => ‘bbb’,
’3′ => ‘ccc’,
));
$a = (array)unserialize($a);
$a[1] = ‘ddd’;
var_dump($a);
?>

Expected result:
----------------
output same results in their versions:
array(3) {
[1]=>
string(3) “ddd”
[2]=>
string(3) “bbb”
[3]=>
string(3) “ccc”
}

Actual result:
--------------
// results before ver5.3.8：
array(3) {
[1]=>
string(3) “ddd”
[2]=>
string(3) “bbb”
[3]=>
string(3) “ccc”
}

// results in ver5.3.10：
array(4) {
["1"]=>
string(3) “aaa”
["2"]=>
string(3) “bbb”
["3"]=>
string(3) “ccc”
[1]=>
string(3) “ddd”
}
