PHP Bug Type: Session related
Bug description: session changes unsaved with register_long_arrays off
Description:
------------
I'm using the ISAPI filter in IIS6.
With register_long_arrays off, the session variables are not always saved.
Note that in my example, I found that assigning $sv=$_SESSION; always
breaks it, but my webpage only does assignments like $sv=$_SESSION['idx']
yet is still broken.
setting "register_long_arrays = On" in php.ini fixes the problem.
Reproduce code:
---------------
<head><title>test.php</title></head>
<html>
<body>
<?php
session_start();
$sv = $_SESSION; //broken!
//$sv['idx'] = $_SESSION['idx']; //ok!
if (isset($_SESSION['idx']))
$i = $_SESSION['idx'] + 1;
else
$i = 0;
$_SESSION['idx'] = $i;
session_write_close();
echo '<p>SESSION START: '.$sv['idx'].'</p>';
echo '<p>SESSION END: '.$_SESSION['idx'].'</p>';
?>
<a href="test.php">test</a>
</body>
</html>
Expected result:
----------------
SESSION START: n
SESSION END: n+1
(after clicking link)
SESSION START: n+1
SESSION END: n+2
Actual result:
--------------
SESSION START: n
SESSION END: n+1
(does not change even after clicking link. Note that older session data is
kept, if idx=3 when requesting the test page, then n=3)
