I have register_globals off as that is (as I udnerstand it) a more
secure approach. ANd it will make hte code messy to use
$_SESSION['varname'] everywhere. I think I'll just copy it to a global
and use it that way.
Which leads to another question ... I thought these two constructs were
equivalent:
$var = "foo";
session_register('var');
.....
$var = "bar";
$var = "foo";
$_SESSION['var'] = $var;
.....
$var = "bar";
I would have thought that in both cases the session data saved at the
end of the script will have $var set to "bar", i.e. it is the value at
the end of the script, not the value at time of registration, that is
saved. Is this incorrect? The docs for session_register() left me
with this impression, and the general session docs suggest that
registering a variable with $_SESSION is equivalent to doing it with
session_register(), and in fact preferable. If they behave
differently, I can't see where the docs say so.
Thanks,
