Bug description:serialize a private attribute give it a bad length string
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.
