Bug description:Storing PDO Statement Class in $_SESSION Corrupts all $_SESSION
variables
Description:
------------
Anytime i assign a new object instance of PDOStatement to a session
variable the session text file goes to zero byte and has no session
information inside. The following code will produce the issue. If you
comment out the 2nd $_SESSION assignment which is the PDO issue the session
will log its information to the sess text file properly and works as
expected. Here is very simple php example that will produce the issue:
<?php session_start(); ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml";>
<head>
<title>PDO Statement Session Test</title>
</head>
<body>
<?php
$_SESSION['regularVariable'] = 'Regular Stuff'; // Works just fine
$_SESSION['pdoVariable'] = new PDOStatement; // zeros the sess* file
?>
</body>
</html>
Test script:
---------------
<?php session_start(); ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml";>
<head>
<title>PDO Statement Session Test</title>
</head>
<body>
<?php
$_SESSION['regularVariable'] = 'Regular Stuff'; // Works just fine
$_SESSION['pdoVariable'] = new PDOStatement; // zeros the sess* file
?>
</body>
</html>
Expected result:
----------------
Test #1 - As is will produce a zero byte php sess* file(No variable
information will be logged in the file and thus not available to follow-up
sessions if there were session variables stored they are lost).
Test #2 - Comment out the pdoVariable line will properly store the other
$_SESSION variables in the sess* file.
