Are there any best practices or guidelines for managing sessions across multiple websites in PHP?

When managing sessions across multiple websites in PHP, it is important to ensure that session data is shared and consistent across all sites. One way to achieve this is by using a centralized session storage mechanism, such as a database or a shared file system. By storing session data in a common location, all websites can access and update the same session information. 

// Set session save path to a shared directory
session_save_path('/path/to/shared/sessions');
session_start();
