No, it is not possible to "undefine" an existing class.

In your case, you should not have several classes that all have the same name : each class should have a different / distinct name, and you should modify the way you are working with those, so your code deals with classes not named ItemClass.

For instance, you could have :

• ItemClass_Type1 in itemclass_type1.php
• ItemClass_Type2 in itemclass_type2.php

and so on -- and those classes could all extend the same base class, if needed / if it makes sense.

(For a while, I thought maybe runkit could help with the "undefining a class" idea ; but there doesn't seem to be a function to do that -- and that extension is not quite stable and shouldn't be used on a production server)
