Description:
------------
wddx session handler is work well for string and integer variables.
But, web server always crash when I tried to recover session variables after php object was saved as session variable.
my php.ini,
session.serialize_handler = wddx
session.save_path = "c:\temp"
Reproduce code:
---------------
<?php
class MyClass {
public $c;
function __construct() {
$this->c = 'foo';
}
function show() {
return $this->c;
}
}
session_start();
if (!isset($_SESSION['c'])) {
$c = new MyClass();
$_SESSION['c'] = $c;
}
print $_SESSION['c']->show();
?>
Expected result:
----------------
foo
Actual result:
--------------
When reload this script, web server should be terminated.
For another serializer such as php or php_binary,
it works well as expected.
