What are the potential pitfalls of not properly setting up session save path in PHP?

If the session save path is not properly set up in PHP, sessions may not be saved or retrieved correctly, leading to issues with user authentication, shopping carts, and other session-dependent functionalities on a website. To solve this issue, ensure that the session save path is set to a valid directory on the server where PHP has write permissions. 

// Set the session save path to a valid directory
session_save_path('/path/to/session/directory');

// Start the session
session_start();
