cookies under php 4.06

okay, i know this is stupid, and i'm gonna kick myself when someone points
out the obvious...

i've just put a site online, and found the server's running an older version
of php (4.06). it's virtual hosting, so i have no control over this... also
can't tell you what OS it's running, but it is windows based...

the code works locally, although i had to change all $_COOKIE to
$HTTP_COOKIE_VARS, same with $_POST, $_SERVER, etc. etc.

i've had a quick look through the archives, and googled, but can't find much
help around for older installs of php.

my code, like i said, the functionality works, but it's just plain not
sending the cookie, my little print statements show up and all, but i get no
error, and i also get no cookie.

<?
$error=2;
require_once("../inc/db.inc.php");
db_connect('babc');
if(isset($HTTP_GET_VARS['logout']))
{
setcookie("UserName", "", time()-(60*60*24));
setcookie("Password", "", time()-(60*60*24));
print "logout";
$error=2;
}elseif(isset($HTTP_POST_VARS['login'])){
$SQL = "...";
$res = mysql_query($SQL) or die( mysql_errno." query error" );
$numRows = mysql_num_rows($res);
if($numRows==1)
{
extract(mysql_fetch_array($res));
setcookie("UserName", $HTTP_POST_VARS['UserName'], time()+(60*10), "/",
$HTTP_SERVER_VARS['SERVER_NAME']);
setcookie("Password", $password, time()+(60*10), "/",
$HTTP_SERVER_VARS['SERVER_NAME']);
print "login - set cookie";
$error=0;
}else{
$error=1;
}
}elseif (isset($HTTP_COOKIE_VARS ['UserName']) && isset($HTTP_COOKIE_VARS
['Password'])){
$SQL = "...";
$res = mysql_query($SQL) or die( mysql_errno." query error" );
$numRows = mysql_num_rows($res);
if($numRows==1)
{
extract(mysql_fetch_array($res));
setcookie("UserName", $HTTP_COOKIE_VARS['UserName'], time()+(60*10), "/",
$HTTP_SERVER_VARS['SERVER_NAME']);
setcookie("Password", $password, time()+(60*10), "/",
$HTTP_SERVER_VARS['SERVER_NAME']);
print "already logged in";
$error=0;
}else{
$error=1;
setcookie("UserName", "", time()-(60*60*24));
setcookie("Password", "", time()-(60*60*24));
print "problem with login, logout";
}
}
?>

> setcookie("UserName", $HTTP_POST_VARS['UserName'], time()+(60*10), "/",
> $HTTP_SERVER_VARS['SERVER_NAME']);
> setcookie("Password", $password, time()+(60*10), "/",
> $HTTP_SERVER_VARS['SERVER_NAME']);
> print "login - set cookie";


sorry for kinda answering my own post... but anyway...

setcookie("UserName", $HTTP_POST_VARS['UserName']);
setcookie("Password", $password);

solves my problem, although means i can't have a time limit on my cookies i
guess... but can set a time limit with another cookie...

Or you could use header()..

1.) I would not store the user's password in a cookie.

2.) As far as I know, set_cookie() has worked the same since PHP3, so your
problem is something else, not the PHP version. Are you sure
$HTTP_SERVER_VARS['SERVER_NAME'] is the same as what's in the location bar
in your browser. If the server name is set up as www.domain.com but the
user is just at http://domain.com the cookie won't set.
