How does PHP handle session data storage and security, especially in shared hosting environments?

PHP handles session data storage by default using files on the server. To enhance security, it is recommended to store session data in a more secure location, such as a database or using secure cookies. In shared hosting environments, it is important to ensure that session data is properly secured and isolated from other users on the server to prevent unauthorized access. 

// Set session save path to a secure location
session_save_path('/path/to/secure/directory');

// Use secure cookies for session ID
ini_set('session.cookie_secure', 1);
ini_set('session.cookie_httponly', 1);

// Start the session
session_start();
