On our development server, sessions handling works fine. On our production server, it doesnt.
phpinfo on the development server shows:
session
Session Support enabled
Registered save handlers files user mm sqlite
Registered serializer handlers php php_binary wddx
phpinfo on the production server shows:
session
Session Support enabled
Registered save handlers files user
Registered serializer handlers php php_binary wddx
What is "mm sqlite" and could it be causing the problem? How do I enable this? What are these settings anyway?
The rest of the settings are common between the two:
Directive Local Value Master Value
session.auto_start Off Off
session.bug_compat_42 On On
session.bug_compat_warn On On
session.cache_expire 180 180
session.cache_limiter nocache nocache
session.cookie_domain no value no value
session.cookie_httponly Off Off
session.cookie_lifetime 0 0
session.cookie_path / /
session.cookie_secure Off Off
session.entropy_file no value no value
session.entropy_length 0 0
session.gc_divisor 100 100
session.gc_maxlifetime 1440 1440
session.gc_probability 1 1
session.hash_bits_per_character 4 4
session.hash_function 0 0
session.name PHPSESSID PHPSESSID
session.referer_check no value no value
session.save_handler files files
session.save_path /tmp /tmp
session.serialize_handler php php
session.use_cookies On On
session.use_only_cookies On On
session.use_trans_sid 0 0
Can the absence of the "mm sqlite" stop PHP sessions from working when shifting from development to production?

There are a couple built-in options for storing session data. The session handler is set in the php.ini under the directive named
session.save_handler
sqlite Optionally, you can store session data in an sqlite database. To do so, use a configuration such as:
session.save_handler = sqlite
session.save_path = /tmp/phpsess.db
mm For high-performance session storage, you can store session data in memory with the mm shared-memory module. You'll need to compile php with the mm module support. Here is a tutorial to configure session handling with mm ( http://www.zend.com/tips/tips.php?id=164&single=1 ). Note that since session date is stored in RAM, you should consider it volatile data, and it's lost with power outage or a reboot.
Note: the link in the above tutorial is outdated. You can retrieve the mm module from the OSSP.org website.
