WordPress core does not use PHP sessions, but sometimes they are required by your use-case, a plugin or theme.
This plugin implements PHP’s native session handlers, backed by the WordPress database. This allows plugins, themes, and custom code to safely use PHP
$_SESSIONs in a distributed environment where PHP’s default tempfile storage just won’t work.
Note that primary development is on GitHub if you would like to contribute:

You may notice there are two sets of tests running, on two different services:
- Travis CI runs the PHPUnit test suite.
- Circle CI runs the Behat test suite against a Pantheon site, to ensure the plugin’s compatibility with the Pantheon platform.
Both of these test suites can be run locally, with a varying amount of setup.
PHPUnit requires the WordPress PHPUnit test suite, and access to a database with name
wordpress_test. If you haven’t already configured the test suite locally, you can run
bash bin/install-wp-tests.sh wordpress_test root '' localhost.
Behat requires a Pantheon site. Once you’ve created the site, you’ll need install Terminus, and set the
TERMINUS_ENV environment variables. Then, you can run
./bin/behat-prepare.sh to prepare the site for the test suite.
If you see an error like “Fatal error: session_start(): Failed to initialize storage module:” or “Warning: ini_set(): A session is active.”, then you likely have a plugin that is starting a session before WP Native PHP Sessions is loading.
To fix, create a new file at
wp-content/mu-plugins/000-loader.php and include the following:
<?php require_once WP_PLUGIN_DIR . '/wp-native-php-sessions/pantheon-sessions.php';
This mu-plugin will load WP Native PHP Sessions before all other plugins, while letting you still use the WordPress plugin updater to keep the plugin up-to-date.

Why not use another session plugin?
This implements the built-in PHP session handling functions, rather than introducing anything custom. That way you can use built-in language functions like the
session_start()in your code. Everything else will “just work”.
Why store them in the database?
PHP’s fallback default functionality is to allow sessions to be stored in a temporary file. This is what most code that invokes sessions uses by default, and in simple use-cases it works, which is why so many plugins do it.
However, if you intend to scale your application, local tempfiles are a dangerous choice. They are not shared between different instances of the application, producing erratic behavior that can be impossible to debug. By storing them in the database the state of the sessions is shared across all application instances.
