What are some best practices to avoid conflicts between session handling and header redirection in PHP?

To avoid conflicts between session handling and header redirection in PHP, it is important to ensure that session functions are called before any output is sent to the browser. This can be achieved by starting the session at the beginning of the script and handling any session-related tasks before performing header redirection. 

<?php
// Start the session before any output is sent
session_start();

// Perform any session-related tasks
$_SESSION['user'] = 'John Doe';

// Redirect to another page
header('Location: another_page.php');
exit;
?>
