The only problem I see with any of these options is that the new arrays
are "superglobals" (not my term) and do not require the use of the
"global" command. For instance:
function myfunc() {
global $HTTP_POST_VARS;
$somevar = $HTTP_POST_VARS["somevar"];
...
}
can now be written as:
function myfunc() {
$somevar = $_POST["somevar"];
}
Sure you can extract the old ($HTTP_) arrays into the new, but you still
don't get the same functionality. (Yes, you could put a 'global
$_POST;' in the new way, but that defeats the purpose of having the new
"superglobals")

put that at the of of your scripts and everything will work ok untill
you
get things moved over.
