What potential issues can arise when using header('Location...') to redirect users in PHP sessions?

One potential issue that can arise when using header('Location...') to redirect users in PHP sessions is that the redirection may not work properly if there is any output sent to the browser before the header function is called. To solve this issue, you can use the ob_start() function at the beginning of your script to buffer the output and prevent any premature output. 

<?php
ob_start();
// Start the output buffer

// Your PHP code here

header('Location: new_page.php');
exit();
// Redirect the user to a new page

ob_end_flush();
// Flush the output buffer
?>
