Object return problem



I have an application in which, I have a page called Detail.php which tries to display a detailed page when I click on some short info link of some user.
I am trying to store this detailed info in an object,

The program flow is like

detail.php --->DbUtitliy.php---->Application utlity.

Application utility class creates a Object from the result that was sent by DbUtility class, (The cretaed Object is OK) then Aplication Utility returns this Object to DbUtility and DbUtility return this Object to detail.php

but this object is not tranfered from Applicationutility to BdUtility

Is there any special method to pass object from one class to other ?

Please help
