When I read it back in and run unserialize() to do a dump, I get this error.WILD GUESS!!! Whatever class objects you had defined before you serialized the data, are not defined when you unserialize the data. You need to load all your class files in both serialize and unserialize scripts -- The class definition is not stored in serialized data, just the class 'data'
A DIFFERENT WILD GUESS!!! :-) I don't think thats the problem - rather I get the impression that there are references (and or resources) inside these SimpleXML objects (e.g. the owning 'document') that cannot be serialized. I would suggest caching the xml string and read that from disk (or where ever your storing stuff) and creating an object from that whenever you need it. I don't believe that you gain much from serializing an object (as compared to creating a new object) - when you unserialize you have pretty much the same overhead as when creating an object (I may be very wrong on this! - I do know that cloning an object is _much_ faster than creating one for instance). -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
