Description:
------------
When you serialize an object with private or protected members, their length names are baddly calculated (maybe because of "These prepended values [which] have null bytes on either side" like the documentation says.
Anyway, this is a problem when you want to write your serialisation into a file and analyse it next.


Note that I'm not using PHP 5.2.17 but 5.2.3. But I haven't read a fix of this problem between both version.

Test script:
---------------
Here is an example:

class Ab {
    private $_i = 0;
    public function __construct() { $this->_i = 1; }
};

$oAB = new Ab();
$str = serialize($oAB);
echo $str;

Expected result:
----------------
O:2:"Ab":1:{s:4:"Ab_i";i:1;}

Actual result:
--------------
O:2:"Ab":1:{s:6:"Ab_i";i:1;}

Note the "s:6" instead of "s:4": this is why the unserialization from this string is impossible.
