How can session management in PHP be optimized to prevent unexpected behavior when downloading files?

When downloading files in PHP, it's important to optimize session management to prevent unexpected behavior such as corrupted downloads or session data interfering with file downloads. One way to solve this is by using session_write_close() to close the session before sending the file to the user, ensuring that no session data is written to the output buffer. 

<?php
session_start();

// Process file download logic here

session_write_close(); // Close the session to prevent interference with file download

// Send the file to the user
