What are the potential pitfalls of using header() for link redirection in PHP?

Using header() for link redirection in PHP can lead to potential pitfalls such as headers already being sent to the browser, causing errors or unexpected behavior. To avoid this, it is recommended to use the header() function along with the ob_start() and ob_end_flush() functions to buffer the output before sending headers. 

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

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