Serializing references - part I

Here goes a patch that should allow serializing references. As for now, it works only for serialize($var), but if it's OK, it would be pretty easy to extend it to other places. The only limitation is that both ends of the reference should be in the serialized variable, otherwise there's no way to know where is it. Please look at it and tell me if anyone has any objections or corrections or "you are doing silly things"s for it. -- Stanislav Malyshev, Zend Products Engineer stas@zend.com http://www.zend.com/ +972-3-6139665 ext.106
