With that in mind, I'd go so far as write PHP code on the receiving pages to
add only the specific things you'd expect to receive into the array instead
of doing a straight array copy.

I guess it's not a BIG deal, though.

Here is a little bit more for a follow up.  Seems this behavior is intended
that way for security reasons.  This is pulled off the annotation from the
PHP site:

------------------
Editor's note: This is a security feature. You shall not trust data coming
from clients.

Remember that you CANNOT override a EXISTING session variable with a
FORM(post), e.g.:

First page:
<?
$something = "blah";
session_register("something");
?>
<form method="post">
<input type="text" name="something">
</post>

And let's say you typed "fla fla" in the something field.

Second page:
<?
SESSION_REGISTER("something");
$something = $something;
echo $something;
?>

The second page will return "blah". You cann't override an existing session
variable with a HTTP POST Variable.

Correct (second page):
<?
SESSION_REGISTER("something");
$something = $HTTP_POST_VARS["something"];
echo $something;
?>

This will return the value you inserted into the input field.
