PHP：对象序列化通过直接文件处理工作，但不通过会话

Question

I'm trying to serialize and unserialize a quite long object -- 250KB compressed -- via session but it's not working.

I've done two tests. The first one consisted on directly serialize and unserialize the object more than once for checking if the problem was the serialization per se but everything ran ok. The second one consisted on writing the serialized object into a file and that worked fine too.

Unfortunately it would be insane to post here or elsewhere all the code itself.

Has anyone dealed with a problem like that or suggest any other test to be done?

Answer 1

The problem was classes with no support to serialization like Zend_Db_Table and Zend_Db_Adapter_Abstract subclasses.

When serializing objects it's needed to go as deep as possible to map every object dependency and treat them and I ended up by giving up serialize what motivated me to post the question in first place.

Thank everyone who tried helping me on this.
