In what situations would using the header function with sleep() be a more appropriate choice for delaying page redirection in PHP?

Using the header function with sleep() would be more appropriate for delaying page redirection in PHP when you want to introduce a delay before redirecting the user to a new page. This can be useful for displaying a message or performing some action before the redirection occurs. 

<?php
// Delay redirection by 3 seconds
header("refresh:3;url=newpage.php");
echo "Please wait while we redirect you...";
sleep(3);
?>
