Note Submitter: neojoda at gmail dot com ---- If you wants to backup a $GLOBALS variable and restore it later, you cannot do: $tmp = $GLOBALS; //do something that modify $GLOBALS $GLOBALS = $tmp because in my tests, I see that $tmp doesn't not has a copy. It seems is a copy by reference. I found this way to do correctly: $tmp = serialize($GLOBALS); //do something that modify $GLOBALS $GLOBALS = unserialize($GLOBALS);
