How can PHP developers ensure session data consistency when navigating between different pages within an application?

To ensure session data consistency when navigating between different pages within an application, PHP developers can use session_start() at the beginning of each page to start or resume a session. They can also use session_write_close() at the end of each page to write session data and release the session lock, ensuring that data is saved and available for subsequent requests. 

<?php
session_start();

// Your PHP code for the page

session_write_close();
?>
