Here's what I came up with:
--script1---
<?php
include('TestClass.php');
session_start();
$obj = $_SESSION['obj'];
// session_register($obj); // recommended not to use - said to be
outdated usage
ob_start();
$obj = &new TestClass();
$obj->setName('MyName');
$obj->display();
header("Location: http://localhost/~mdl/webProj/photoAlbum2/receive.php";);
ob_flush();
?>
---script2---
<?php
include("TestClass.php");
session_start();
$newObj = $_SESSION['obj']; // this works
//$_SESSION['obj'] = $newObj; // this doesn't work
$_SESSION['obj']->display(); //
$newObj->display(); // this doesn't
$_SESSION = array(); // unsets session having effect that script fails on
every second call
?>
My only remaining question is why the session fails every second time if the
session is emptied and destroyed. Shouldn't script1 initialize a totally new
session and populate with fresh session vars?

It might be worth noting that if you are using php4 remember to pass
your object by reference when setting/retrieving from the session.
