What potential issues can arise when using ob_start() and ob_end_flush() in PHP scripts?

One potential issue that can arise when using ob_start() and ob_end_flush() in PHP scripts is that output buffering may not be properly managed, leading to unexpected output or errors. To solve this issue, it's important to ensure that ob_end_flush() is always called to flush the output buffer and send the buffered output to the client. 

<?php
ob_start();

// Your PHP code here

// Ensure that ob_end_flush() is called to flush the output buffer
ob_end_flush();
?>
