PHP Bug Type: Session related
Bug description: Assign $_SESSION to an empty array doesn't work
Description:
------------
Output for Test.php
Current SID: 1e2rcu3s63pv5r0m0omuckmmc6
$_SESSION => array(0) { }
--------------------------------------
Output for Test.php?set=1
Current SID: 1e2rcu3s63pv5r0m0omuckmmc6
Session has been set with 'a' and 'b'
$_SESSION => array(2) { ["a"]=> string(3) "aaa" ["b"]=> string(3) "bbb" }
--------------------------------------
Output for Test.php?reset=1
Current SID: 1e2rcu3s63pv5r0m0omuckmmc6
Session has been set with empty array and new SID is regenerated.
New sid: hathl18bl00gedoqeia2q6dq36
$_SESSION => array(0) { }
--------------------------------------
After go throught these 3 URL, $_SESSION should be equal to empty array
before regenarate new session id.
But it get wrong here:
Change current session id (hathl18bl00gedoqeia2q6dq36) with old session id
(1e2rcu3s63pv5r0m0omuckmmc6) in cookie and enter Test.php without any get
method.
$_SESSION should be an empty array but it show this:
Current SID: 1e2rcu3s63pv5r0m0omuckmmc6
$_SESSION => array(2) { ["a"]=> string(3) "aaa" ["b"]=> string(3) "bbb" }
Reproduce code:
---------------
session_start();
echo 'Current SID: '.session_id().'<br/>';
if(isset($_GET['set']))
{ $_SESSION=array('a'=>'aaa','b'=>'bbb');
echo 'Session has been set with \'a\' and \'b\''.'<br/>';
}
if(isset($_GET['reset']))
{ $_SESSION=array();
session_regenerate_id();
echo 'Session has been set with empty array and new SID is
regenerated.'.'<br/>';
echo 'New sid: '.session_id().'<br/>';
}
echo '$_SESSION => ';
echo var_dump($_SESSION).'<br/>';
Expected result:
----------------
Current SID: 1e2rcu3s63pv5r0m0omuckmmc6
$_SESSION => array(0) { }
Actual result:
--------------
Current SID: 1e2rcu3s63pv5r0m0omuckmmc6
$_SESSION => array(2) { ["a"]=> string(3) "aaa" ["b"]=> string(3) "bbb" }
