hello! i tried this script both on windows and linux with PHP 4.2.3
installed. I saw, that the serialized code could be highly redundant,
depending on serializing the object or it's refference. there's also a
problem around the new constructor, or i guess, the problem might be at
copying objects with the '=' operator...
