PHP Bug Type: Session related
Bug description: session_start defect and not in sync with $_SESSION
Description:
------------
The constant SID is not defined if a session is started with
$_SESSION['bla'] = 'dummy'.
So you have to call session_start to get the SID constant.
But a call to session_start will kill a session that was already started
with $_SESSION['bla'] ='dummy'.
Reproduce code:
---------------
// register globals is off
error_reporting(E_NOTICE);
$_SESSION['dummy'] = 'started';
echo '<pre>';
echo "session data before call to session_start:\n";
print_r($_SESSION);
echo "SID is defined before call to session_start? " . (defined('SID') ==
true?'yes':'no');
echo "\n";
session_start();
echo "SID is defined after call to session start? " . (defined('SID') ==
true?'yes':'no');
echo "\n";
echo "session data after call to session_start:\n";
print_r($_SESSION);
exit;
Expected result:
----------------
SID should be defined when a session is started with $_SESSION and
session_start should handle the call to itself as if it was called twice
when $_SESSION is used.
Actual result:
--------------
session data before call to session_start:
Array
(
[dummy] => started
)
SID is defined before call to session_start? no
SID is defined after call to session start? yes
session data after call to session_start:
Array
(
)
