Wouldn't it be possible to serialize the object in destructor of the class and unserialize from the constructor?
As in serialize($this)?? Think about it for a while and you'll see why
that's not really a great idea.
Firstly, where do you store the serialized object?
Secondly, in the constructor you will be creating a new object, not
populating the current object.
The sort of thing I think you're thinking about is the functionality
provided by __sleep and __wakeup. Look them up in the manual for full
details.
Of course none of that changes the fact that you cannot serialize resources.

Hi there,
You would use a blob or text field.
You will have to serialize the object before saving it to db.
Then when you retrieve it, you will have to deserialize it and then eval()
the object so as to active all the values.
It's unserialize not deserialize, and there's no need to eval anything,
just make sure you have either included the class definition before
unserializing it or have an __autoload function defined.
Remember that you cannot serialize resources, so you must make sure you
close any open resources in the __sleep method, and you can recreate
them during unserialize using a __wake method.
