How many times you were told that you're wrong? $_SESSION['foo'] and
$foo are only related if register_globals is turned on. A simple test:

<?php
session_start();

if (isset($_GET['show'])) {
print '<pre>';
print_r($_SESSION);
var_dump($foo);
var_dump($bar);
print '</pre>';
} else {
$_SESSION['foo'] = 23;
$_SESSION['bar'] = 42;
}
print "<a href='{$_SERVER['PHP_SELF']}?show'>next</a>";
?>

After calling the script and clicking the link, the result with
register_globals = ON will be:

Array
(
[foo] => 23
[bar] => 42
)
int(23)
int(42)

This is what the OP got. Now the same thing with register_globals = OFF:

Array
(
[foo] => 23
[bar] => 42
)

Notice: Undefined variable: foo in ...
NULL

Notice: Undefined variable: bar in ...
NULL

This is how it should be on a properly configured system.
