[thelist] [PHP Newbie] Accessing Object attributes from a _S ESSION variable

You can store your objects in session but you must have the class 
declared prior to session_start():

require_once('classes/person.php'); // declaration of class person

You'll get rid of the __PHP_Incomplete_Class Object

Default session handler uses serialize to store session variables so 
there is no advantage in doing the same in your code.
