Are there any best practices for handling sessions in PHP when using include statements?

When using include statements in PHP, it's important to handle sessions properly to ensure session data is maintained across included files. One best practice is to start the session before including any files that rely on session data, and to make sure to call session_write_close() before including any files that do not need to write to the session. This helps prevent session data from being locked and ensures smooth operation of your PHP application.

<?php
session_start();

// Include files that rely on session data
include 'file1.php';
include 'file2.php';

session_write_close();

// Include files that do not need to write to the session
include 'file3.php';
?>
