Help with PHP/Oracle and serializing data

I'm developing a web application and would like to be able to store the state of the application in an Oracle table by serializing a bunch of variables and storing them in the database. Has anyone done this? What datatype would be best to use here? I'm not serializing too much data now, but other applications that we do in the future may. Would this be a place to use a CLOB or should I stick with varchar2?
