What role does the UTF-8 Byte-Order-Mark play in causing header-related errors in PHP?

The UTF-8 Byte-Order-Mark (BOM) can cause header-related errors in PHP because it adds extra bytes at the beginning of the file, which can interfere with the header() function when sending HTTP headers. To solve this issue, you can remove the BOM from your PHP files by saving them without the BOM in your text editor. 

<?php
ob_start();
header('Content-Type: text/html; charset=utf-8');
ob_end_flush();
