_php_incomplete_class Object with serialization unserialize

__php_incomplete_class Object with serialization unserialize
I am dealing with a shopping cart class, because I have a special handling of the $_session, now need to put the shopping Cart object information into the $_session, directly processing object into my $_session inside is a failure, I have it serialized processing.

There is no problem with processing, but there is an error in calling the deserialized member function, __php_incomplete_class the problem of object.

The problem is very simple, that is, the instance of deserialization does not find the definition of the class, the processing method is very simple, the definition of the relevant class is placed in the session_start ();

Here is a way to add a deal of thought:

When a object is unserialized and its class definition doesn ' t exist
It becomes an instance of "__php_incomplete_class".

No problem ... however, what's annoying me is so you cannot treat it
Like a vanilla flavoured "stdClass", object and set its member variables.

Get_object_vars () would allow your to get a property, but you cannot set any!
Try my example:

Force a __php_incomplete_class Object
$sleepstring = ' o:12: ' Missingclass ': 1:{s:5: "MyVar"; s:11: "Hello World";} ';
$OBJ = Unserialize ($sleepstring);

Test, its broke!
$isbroken = Is_a ($Obj, ' __php_incomplete_class ');
Var_dump ($isbroken); BOOL (TRUE)

Test properties
Var_dump ($OBJ->myvar); NULL, and raises e_notice
$vars = Get_object_vars ($OBJ);
Var_dump ($vars [' myvar ']); String (one) "Hello World", hooray!
?>


Anyone know a hack/workaround to set a value in the object?

*one idea*
Could construct a StdClass instance, copy the proprties into it,
And then hack the resulting string, the object is serialized again.
Like ?>
However:this wouldn ' t work on session sleep!
