Bug description: key in array inaccessible if unserialized as string
Description:
------------
If an array is unserialized where a numerical key is represented as a
string (s:3:"123"), the key and its value become inaccessible via direct
access ($array[123]) as well as via isset, is_*, array_key_exists,
var_dump, etc. The key and value are accessible via var_dump of the whole
array, or via foreach.
Reproduce code:
---------------
<?php
$bob = unserialize('a:1:{s:5:"words";a:1:{s:3:"123";s:3:"foo";}}');
echo var_dump($bob);
echo var_dump($bob['words']['123']);
$id1 = '123';
echo var_dump($bob['words'][$id1]);
$id2 = 123;
echo var_dump($bob['words'][$id2]);
echo
0+isset($bob['words']['123']),0+isset($bob['words'][$id1]),0+isset($bob['words'][$id2]);
echo
0+array_key_exists('123',$bob['words']),0+array_key_exists($id1,$bob['words']),0+array_key_exists($id2,$bob['words']);
?>
Expected result:
----------------
array(1) {
["words"]=>
array(1) {
[123]=>
string(3) "foo"
}
}
string(3) "foo"
string(3) "foo"
string(3) "foo"
111111
- OR -
array(1) {
["words"]=>
array(1) {
["123"]=>
string(3) "foo"
}
}
string(3) "foo"
string(3) "foo"
string(3) "foo"
111111
Actual result:
--------------
array(1) {
["words"]=>
array(1) {
["123"]=>
string(3) "foo"
}
}
