Dave,
From php.net, the section on session functions, and the function
"session_set_cookie_params", it was posted by a person who just doesn't
want to receive junk mail (it was not me). Basically you have to tell
the browser that the domain is domain.com, not sub.domain.com. It's
more of a client issue than a server issue.

ok. hope this works. first time posting
heres a quick little snippet I came up with to pass sessions between
lots of sub domains or c names. it also contains an array walker for
reading and outputting the contents of the current array(in this case i
use it for http_session_vars)
ex:
www.fluidideas.com
chat.fluidideas.com
mypage.fluidideas.com
www.mypage.fluidideas.com
these will all have access to the session.
!!!BEGIN CUT!!!
session_set_cookie_params ( time()+9999999 , "" , ".fluidideas.com" );
if ( $HTTP_COOKIE_VARS[session_id_set] )
{ session_id( $HTTP_COOKIE_VARS[session_id_set] ); }
session_start ();
Function session_walker($Array)
{
If ( !Is_Array($Array) ) Return $Array;
Reset($Array);
While( List( $Key, $Value ) = Each( $Array ) )
{
If ( Is_Array( $Array[ $Key ] ) )
{
$Array[ $Key ] = session_walker( $Array[ $Key ] );
}
Else
{
echo "key -> " . $Key . "
\n";
echo "value -> " . $Value . "
\n";
}
}
Return $Array;
}
!!!END CUT FOR SESSION INCLUDE!!!
!!!BEGIN CUT!!!
$user_session_id = session_id();
setcookie("session_id_set","$user_session_id",time ()+9999999,"",
".fluidideas.com", "");
session_register("user");
session_register("password");
session_register("email");
!!!END CUT FOR LOGIN!!!
now this example will allow the session to carry the data from sub
domain to sub domain and it only has one flaw that i've noticed. NS 4.7
is the only browser I've seen this in (also use mozilla .8 and IE5.5)
but if the domain doesnt contain a c name the sessions wont pass.
ex: fluidideas.com not
www.fluidideas.com
If someone can come up with a fix to this please email me. Thanks

Hi
Why does the following code allow me to keep the same session when in
the same sub domain (ie admin.localhost), yet not when I goto another
related domain eg main.localhost?
I would like to have the same session on the related domain. I bet
the solution is really simple <grin>!...
Kind Regards
Dave.
Using IE6. Win NT, Apache 1.3.27, PHP 4.3.2.
php.ini file - shown at end of message (apologies for length).. is
actually a copy of a PHP4.3.0 ini file (problem here?)
hosts file in windows:
127.0.0.1 localhost
127.0.0.1 admin.localhost
127.0.0.1 main.localhost
httpd.conf
setup for VirtualHosts
eg
ServerName admin.localhost.com
// session_test.php -- located in admin.localhost
<?
session_start();
echo "id is " . session_id();
?>
a href="http://admin.localhost/session_test1.php" next
a href="http://main.localhost/session_test2.php" next
// session_test1.php -- located in admin.localhost
<?
session_start();
echo "id is " . session_id();

// session_test2.php -- located in main.localhost
