Could verify this with PHP 4.3.0-dev 2002-07-31 on Compaq Tru64:
$test_array =
'a:1:{s:12:"fas";a:6:{s:10:"mkey_index";s:12:"fas";s:9:"save_typ
e";i:1;s:6:"German";i:;s:7:"English";i:;s:6:"Slovak";i:;s:5:"Czech";i:;}}';
$result_array = unserialize($test_array);
print_r($result_array);
Returns nothing.
On the same machine this works:
$array = array(1,2,3,9,7,4,5,12,"lala"=>array("test"=>1,2,3,3));
$serialized_array = serialize($array);
print_r($serialized_array);
$result_array = unserialize($serialized_array);
print_r($array);
print_r($result_array);
Results as expected in:
Array
(
[0] => 1
[1] => 2
[2] => 3
[3] => 9
[4] => 7
[5] => 4
[6] => 5
[7] => 12
[lala] => Array
(
[test] => 1
[0] => 2
[1] => 3
[2] => 3
)
)
Array
(
[0] => 1
[1] => 2
[2] => 3
[3] => 9
[4] => 7
[5] => 4
[6] => 5
[7] => 12
[lala] => Array
(
[test] => 1
[0] => 2
[1] => 3
[2] => 3
)
)
Are you shure, your serialized Array is correct?

I try unserialize array and everything goes nice when the array has all
elements filled. When one of element is empty unserialize returns
false
More specific:
PHP 4.0.6
"""""""""
a:1:{s:12:"fas";a:6:{s:10:"mkey_index";s:12:"fas";s:9:"save_type";i:1;s:6:"German";i:;s:7:"English";i:;s:6:"Slovak";i:;s:5:"Czech";i:;}}
unserialize returns array where empty elements are replaced by 0
___________________________________________________________
PHP 4.2.2
"""""""""
a:1:{s:12:"fas";a:6:{s:10:"mkey_index";s:12:"fas";s:9:"save_type";i:1;s:6:"German";i:;s:7:"English";i:;s:6:"Slovak";i:;s:5:"Czech";i:;}}
unserialize returns false (if no empty elements, unserialize returns
correct array)
