What are the potential pitfalls of using PHP headers for page refreshes?

Using PHP headers for page refreshes can cause issues such as headers already sent errors if there is any output before the header function is called. To avoid this, you can use output buffering to capture any output before sending headers. 

<?php
ob_start();
// Your PHP code here

// Redirect to another page after 5 seconds
header("refresh:5;url=anotherpage.php");

ob_end_flush();
?>
