I was trying to test the session via two pages, test.php and test2.php. Following are the scripts and results come up:

test.php
<?php
session_start();
$_SESSION["user"]="foo";
echo "set:".$_SESSION["user"];
unset($_SESSION);
echo "<br>unset:".@$_SESSION["user"];
?>

result on page:
set:foo
unset:

test2.php
<?php
session_start();
echo "set:".$_SESSION["user"];
echo "<br>unset:".@$_SESSION["user"];
?>

result on page:
set:foo
unset:foo

I've also tried to put up a session_destory() in test.php, that helps to unset the variable, but simply the session no longer exists.

Does anyone has the same problem, or any answers to this issue?
