In the context of PHP sessions, what steps can be taken to ensure consistent behavior and data integrity across different server configurations?

To ensure consistent behavior and data integrity across different server configurations in PHP sessions, it's important to set the session save path to a shared location that is accessible by all servers. This will prevent session data from being lost or inconsistent when users switch between servers. 

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