WP Session Manager

Merely use the superglobal $_SESSION array: $_SESSION['user_name'] = 'User Name'; // A string $_SESSION['user_contact'] = array( 'email' => 'user@name.com' ); // An array $_SESSION['user_obj'] = new WP_User( 1 ); // An object

This depends on your PHP installation's configuration. Please read the PHP manual for more details on configuration.

Absolutely! As of version 2.0, this plugin will create a new table for WordPress to store session data. In general, this is more efficient long-term than using options for data storage. However, if your system does not allow creating a table, add the following to wp-config.php to use the options table instead: define( 'WP_SESSION_USE_OPTIONS', true );

PHP 5.6 was designated end-of-life and stopped receiving security patches in December 2018. PHP 7.0 was also marked end-of-life in December 2018. The minimum version of PHP supported by WP Session Manager is now PHP 7.1. If your server is running an older version of PHP, the session system will not work! To avoid triggering a PHP error, the plugin will instead output this notice to upgrade and disable itself silently. You won't see a PHP error, but you also won't get session support. Reach out to your hosting provider or system administrator to upgrade your server.

WP Session Manager overrides PHP's default session implementation with its own custom handler. Unfortunately, we can't swap in a new handler if a session is already active. This plugin hooks into the plugins_loaded hook to set things up as early as possible, but if you have code in another plugin (or your theme) that attempts to invoke session_start() before WP Session Manager loads, then the custom handler won't work at all. Inspect your other plugins and try to find the one that's interfering. Then, reach out to the developer to explain the conflict and see if they have a fix.
