yes
you will need to [man]serialize[/man] it first though.
$myobj = new yourclass();
$serialized_myobj = serialize($myobj);
then on the page you pass the object to, use [man]unserialize[/man] to put the objedct back together again. you will also need to make sure the class definition is included in the page your pass to. serialize only stores the objects data, not the class itself.
