What are the best practices for handling sessions and redirection in PHP to ensure a smooth user experience?

When handling sessions and redirection in PHP, it is important to ensure that sessions are properly started and managed before performing any redirection. This can help maintain user state and prevent errors during navigation. Additionally, using header redirection functions can help seamlessly direct users to different pages without disrupting their experience.

<?php
session_start();

// Perform necessary session operations here

// Redirect user to a new page
header("Location: new_page.php");
exit;
?>
