>>> USE OF CLASSES, OBJECTS and SESSIONS. <<<

If you have an object, or an array that used in many pages, you need to serialize/unserialize it.

exampla:
include("class.example.php");
$object = new example ();

$se_obj = serialize($object);

$_SESSION['se_obj']=$se_obj; // here, the object is is the SESSION as a global variable
It won't be destroyed when you change pages.

when you then got on the next page and so a session_start(), you must have included a class definition first.
and you don't habe included the class description, your object will still not break.

Just do a:
include("class.example.php");
$object = unserialze($_SESSION['se_obj']);

and all is fine.
