What are the best practices for handling sessions in PHP scripts?

When handling sessions in PHP scripts, it is important to ensure the security and integrity of the session data. To do this, it is recommended to use session_start() at the beginning of each script that needs to access session data, regenerate the session ID periodically to prevent session fixation attacks, and properly destroy the session data when it is no longer needed.

// Start the session
session_start();

// Regenerate the session ID periodically
if (mt_rand(1, 100) == 1) {
    session_regenerate_id(true);
}

// Destroy the session data when it is no longer needed
session_destroy();
