c++ and php

Hi,
I am using cpp with php 4.3.2 as:
$object = myphpclass();
$object->setstring("Hello how are you");
which is working fine.
Now when I register $object in session and use it in another page like this:
$obj=$_SESSION['object'];
$obj->getstring()
Following error come:
Fatal error: underlying object is of wrong type in getstring().
Please help

Regards

Hi,
should I think no one have answer of my question.

think you could post the code for the class?
meanwhile, it is my assumption that getstring() returns something...
hence you'd have to do:

$str = $obj->getstring()
echo $str
