You are probably expecting PHP to use the $_POST and $_GET as global variables. PHP used to be setup this way, back in the day, but newer versions require you to explicitly reference these variables.
If $id is not set, the call to setdefault($id,0) will generate a warning. A function like setdefault does not work in PHP. Use this instead.
