How can output buffering be used to prevent header-related errors in PHP?

Output buffering can be used to prevent header-related errors in PHP by buffering the output before any headers are sent to the browser. This allows you to modify headers even after content has been sent. To implement this, you can use the ob_start() function at the beginning of your PHP script to turn on output buffering, and then use ob_end_flush() at the end of your script to flush the buffer and send the output to the browser. 

<?php
ob_start();

// your PHP code here

ob_end_flush();
?>
