What is the difference between:
$familyname = getvar("familyname");
and
$familyname = getvar('familyname');
What do single quotes do, as a general rule, that double cannot (he asks remembering
something, but not sure what)?

Re: [PHP] Session: I RTFM
John,
PHP looks for "$vars or {$vars} to parse in the string" when double quotes
are used... whereas when single quotes are used, it won't parse/substitute
the vars.
So, when you're not using $vars, using single quotes will be marginally
faster... perhaps not important on small sites, but very important on big
ones, and a decent habbit to get into :)

Re: [PHP] Session: I RTFM
I haven't followed the rest of the thread, but how about using a
function?
function getvar ($varname)
{
if (isset ($_POST[$varname])
{
$_SESSION[$varname] = $_POST[$varname];
return $_POST[$varname];
}
elseif (isset ($_SESSION[$varname]))
return $_SESSION[$varname];
}
session_start();
// You don't need session_register anymore
$familyname = getvar('familyname');
and so on--just one line per variable.
Hope this helps.
Cheers,
Marco

The FM manual says:
"$_SESSION (or $HTTP_SESSION_VARS with PHP 4.0.6 or less) is recommended"
So I am using "PHP Version 4.1.2" (and "4.2.3" on my localhost to test offline)
Ok. I quit using $HTTP_POST_VARS["familyname"].
With a little rethinking, I have this working, I hope.
Now ... is there a cleaner way to assign my variable "familyname"?
Pseudo code:
if _post["familyname"] exists set session variable
(no sense in setting it until I post it)
if _session["familyname"] exists, $familyname = $_SESSION["familyname"];
I'll have about 30 variables. Going to be alot of lines. There must be an easier,
cleaner way?

if (isset($_SESSION["familyname"]))
