How can output buffering be used to prevent header modification issues in PHP scripts?

Output buffering can be used to prevent header modification issues in PHP scripts by capturing all output before it is sent to the browser. This allows headers to be modified or sent without causing errors. To implement output buffering, you can use the ob_start() function at the beginning of your script and ob_end_flush() at the end to send the buffered output to the browser.

<?php

ob_start();

// Your PHP code here

ob_end_flush();
