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

Output buffering can be used to prevent header modification errors in PHP scripts by buffering the output before any headers are sent. This allows you to modify headers without encountering errors, as headers must be sent before any content. By using output buffering, you can capture the output of your script and then send headers without any issues. 

<?php
ob_start(); // Start output buffering

// Your PHP script here

// Modify headers
header('Content-Type: text/html');

ob_end_flush(); // Flush the output buffer
?>
