ID: 54290 Comment by: hanskrentel at yahoo dot de Reported by: frederic dot hardy at mageekbox dot net Summary: Class which extends from \SplFileObject is not serializable Status: Open Type: Bug Package: SPL related PHP Version: 5.3.5 Block user comment: N Private report: N New Comment: According to the code it is intended that you can not serialize it. Which can make sense as the file itself already is a serialized form of the object it represents. However different to DOMDocument where serialization wouldn't make much sense (XML is a serialization already), in the SplFileObject case, Serialization is *explicitly* forbidden. The internal state of the object can not be preserved by serialization, therefore it is just not possible. This ticket can be closed as a duplicate of #46646 in my eyes or it needs to be turned into a feature-request, so that implementing Serializable might become possible - like it is with DOMDocument.
