The point is, you don't need to use serialize() and unserialize(), just
assign the class object to the session variable directly, i.e.:

$_SESSION["obj"] = $obj;

...

$obj = $_SESSION["obj"];


Beware the warning in the manual:

"Some types of data can not be serialized thus stored in sessions. It
includes resource variables or objects with circular references (i.e.
objects which passes a reference to itself to another object)."
