How can the concept of output buffering be utilized to prevent header-related errors in PHP scripts that include templates like header.php and footer.php?

When including templates like header.php and footer.php in PHP scripts, header-related errors can occur if output is sent to the browser before headers are set. To prevent this, we can utilize output buffering in PHP. By turning on output buffering at the beginning of the script, we can capture all output and prevent it from being sent until headers are set. This ensures that headers can be set without any issues. 

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

// Include header.php and other template files
include 'header.php';

// Rest of your PHP script goes here

// Include footer.php
include 'footer.php';

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