Note Submitter: Reason: useless ---- When I first was writing my last comment, I was thinking that somehow there was a php bug causing two separate global namespaces. As I was composing the post I realized that perhaps the problem was unsetting the variable, and removed all my references to two namespaces. Now in reviewing some of the posts below which discuss the issue of unsetting global variables as an issue, I think that the unsetting is the problem, and that the preferred method is not to unset them but assign null to them.
