Bug #71187 [NEW]: session_regenerate_id(): Failed to create(read) session
From: akauffman at ne4u dot com
Operating system: Ubuntu 14.04 LTS
PHP version: 7.0.1
Package: Session related
Bug Type: Bug
Bug description:session_regenerate_id(): Failed to create(read) session
Description:
------------
There seems to be a type casting problem with custom session handlers
(specifically the memcached module) when session_regenerate_id() is
called. Perhaps related to a null return value. It looks like it was
introduced around 7RC3.
Error:
PHP message: PHP Catchable fatal error: session_regenerate_id(): Failed
to create(read) session ID: user
Test script:
---------------
Problem:
<?php
set_ini('session.save_handler','memcached');
set_ini('session.save_path','host1:11211');
session_start();
$_SESSION['value'] = session_id();
session_regenerate_id();
?>
Work around:
<?php
set_ini('session.save_handler','memcached');
set_ini('session.save_path','host1:11211');
class MemcachedSession extends SessionHandler
{
public function read($session_id) {
return (string)parent::read($session_id);
}
}
$sess = new MemcachedSession();
session_set_save_handler($sess, true);
session_start();
$_SESSION['value'] = session_id();
session_regenerate_id();
?>
Expected result:
----------------
Shouldn't have to implement a workaround.
