How to get oid after table insert? [postgresql]

Hello. I am working on a site using PHP (obviously) and PostgreSQL. I am currently using the oid as a key on a table. I would like to return the user to the same record after INSERTing it, but I cannot figure out how to get the oid of the record after doing an INSERT. Ideally, I would like something like: So, how do I insert a new record into the database, and get the oid of the record I just inserted? thanks
