Thank you Andrew... Now it all makes perfect sense. Good grief! there's

That's not specific to PHP. It's just how http works, so it's the same
for ASP, Perl, I suspect Java and most (if not all) other languages.
There might be a language that sets a cookie when you assign a value
to a special cookie variable, but I'm not familiar with any.

Unless I was doing something differently when I originally wrote this in
PERL I don't recall having this issue. At that time I would set the
cookie and then redirect (load the index with the full menu) if cookie
existed.
Geez! now my $_SESSION isn't persisting to the next page when the screen
refreshes. The only thing preventing me from gouging out my eyes right
now is that I know I'll get this stuff. It's just a matter of time...
The "problem" that you are encountering is because the $_COOKIE array is
"populated" when the script is executed. More then likely the other
languages that you used, would allow you to set a cookie and then they
would enter them into the "global" array for you, and not make you wait
until the next page load.
You could accomplish this yourself by making a wrapper function for the
setcookie() function and have your function set the data using
setcookie() and having it enter the data directly into the $_COOKIE array.
Something like this should do the trick
<?php
/*
bool setcookie ( string $name
[, string $value
[, int $expire
[, string $path
[, string $domain
[, bool $secure
[, bool $httponly ]]]]]] )
*/
function mySetCookie($name,
$value=null,
$expire=0,
$path='/',
$domain=null,
$secure=FALSE,
$httponly=FALSE) {
if ( is_null($domain) )
$domain = $_SERVER['SERVER_NAME'];
if ( setcookie( $name, $value, $expire,
$path, $domain, $secure, $httponly) ) {
$_COOKIE[$name] = $value;
return true;
}
return false;
}
?>
