in PHP 4.0.1pl2 something seems to be broke regarding serializing objects of type "stdClass".
A class with an object of type "stdClass" cannot be unserialized and used.
The following example WONT work:
class Foo
{
	var $object;
	function Foo()
	{
	$object = mysql_fetch_object($result);
	}
}
/* code */
$myfoo = new MyFoo();
$s_myfoo = serialize($myfoo);
$newfoo = new MyFoo();
$newfoo = unserialize($s_myfoo);
/***************/
echo $newfoo->object->what_ever;
gives the following error
"The script tried to execute a method or access a property of an incomplete object" - even though "stdClass" definition exists and is loaded.

Works for me. Are you sure you are using 4.0.1pl2?
Try latest CVS, then.

Tried again.
The following does not work in PHP Version 4.0.1pl2!
(works fine in 4.0.0)
System Linux heaven 2.2.16 #1 Tue Jun 13 13:58:52 CEST 2000 i586 unknown.

Exact Code (needs reloading once)
---------------------------------
class Foo
{
	var $object;
	var $str;

	function Foo()
	{
		$this->object->mytest = "testing";
		$this->object->other = "hallo";

		$this->str = "the following works";
	}
}

$myfoo = new Foo();
print("creating foo()<br>\n");

$s_myfoo = serialize($myfoo);
printf("serializing foo() = %s<br>\n", $s_myfoo);

$newfoo = new Foo();
$newfoo = unserialize($s_myfoo);
print("unserializing newfoo<br>\n");

print("printing variable...<br>\n");
printf("newfoo->str = %s<br>\n", $newfoo->str);
printf("newfoo->object->mytest = %s<br>\n", $newfoo->object->mytest);

May need to be "reloaded" once after opening the page.
