Redirect use back after execution

Hello I'm making vbulletin foru hack, that allows to rate members my code is just 50 lines, I set link to my script from vBulletin page, and after it has been clicked code executes, and then i want to return user to the page where he clicked the link leading to my code, i was wondering how can this be done, use REFERER and then header("Locatiom: $REFERER";), will this work? Thank you very much
