What are the advantages of using ob_start() and ob_end_clean() functions in PHP scripts?

When working with PHP scripts that generate output, using ob_start() and ob_end_clean() functions can be beneficial. ob_start() allows you to buffer the output generated by the script, which can be useful for manipulating or capturing the output before it is sent to the browser. ob_end_clean() then discards the buffer contents without sending it to the output, which can be helpful in cases where you want to prevent certain content from being displayed. 

<?php
ob_start();

// Your PHP script code here

$output = ob_get_clean();

// Manipulate or use $output as needed
?>
