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

Output buffering can be used to prevent header errors in PHP by buffering the output before any headers are sent to the browser. This ensures that headers are only sent once all the output has been generated, preventing any errors that may occur if headers are sent after content. To implement this, you can use the ob_start() function at the beginning of your PHP script to start output buffering. 

<?php
ob_start();

// Your PHP code here

ob_end_flush();
?>
