In what situations should PHP developers use the exit function after using the header function to redirect to a different URL?

When using the header function to redirect to a different URL in PHP, it is important to use the exit function immediately after to prevent any further code execution that could potentially interfere with the redirection process. This ensures that the redirect happens smoothly without any unexpected behavior. 

<?php
header("Location: https://www.example.com");
exit;
?>
