Introduction

Found at: https://github.com/Dynom/SessionHandler

This session handler has one purpose: To provide a reliable session backend by offering a redundant storage system for PHP sessions. Easily implementable for existing and new systems.

When not to use it

You can always use it, but if you only have one backend system it's much more efficient to use the default features PHP offers.

Installation

Make sure you meet the requirements for the drivers you wish to use, for example: Make sure you have a MySQL server if you want to use the MySQL diver, etc.
Download the SessionHandler, and make it available in your project(s). You can do this in a couple of ways, either hack it in your project or use the 'auto_prepend_file' php.ini setting. The test.php shows a possible way of including it in your codebase.
Define the drivers and their configuration.
Set the config directive 'save_handler' to 'user'. Do this either in your php.ini, webserver option directive (such as .htaccess) or in your script (Like so: ini_set('session.save_handler', 'user');)

..And done!

Drivers

At moment of writing there are two, the Memcache and the MySQL, but more will be added later. Writing your own is extremely easy, extend the abstract class D_SessionDriver_Abstract and implement the missing parts. Look at the available drivers on how to do that.

Memcache Make sure you have the 'Memcache' extension (note that there are multiple Memcache extension.)
MySQL Make sure you compiled PHP with MySQL support
