Sessions variables with register globals off

This use of sessions generally (expressed simply) has worked for me:
sess1.php:
<?php
session_start();

session_register("auth");

$auth = "true";
echo "<a href=\"sess2.php\">here</a>";
?>
sess2.php
<?php
session_start();

if ($auth) .......

?>
$auth will be set to true in the second script. However, if a server has register globals set to off, this will not work. Is there another way to set up a session variable that will work in an environment with register globals off? (I am trying to implement an authentication scheme?)

You would access those variables in the same manner that you would any other variable when register globals is set to off

Thnx Spookster - I had looked at that, and tried the following, but nothing prints out, so it does not seem to work?

sess1.php
<?php

$_SESSION['session_var']= $auth;

$auth = "yes";
echo "<a href=\"sess2.php\">here</a>";
?>

sess2.php
<?php

echo $_SESSION["auth"];

?>

try
$HTTP_SESSION_VARS['session_var'];

You forgot session_start() in your code; without it you won't find anything in $_SESSION.

"//session_start() is not strictly required !//"

But I tried it anyway, and same result. Did not yet try carl's suggestion

//session_start() is not strictly required !//

... actually depending on the php.ini configuration that may not be the case , sorry :o

session_start() is not required if session.auto_start is 'on' in the php.ini , and it appears that the 4.3.0 default php.ini at least is set 'off' though most commercial hosts seem to have it set on.


also you should be checking for echo $_SESSION['session_var']; or $HTTP_SESSION_VARS['session_var']; as bcarl suggests not 'auth' which ='yes'

either way it will be empty ;)

$_SESSION['session_var']= $auth;
$auth = "yes";

should be

$auth = "yes";
$_SESSION['session_var']= $auth;

etc

OK, thanks much!
