What potential issues can arise when saving PHP scripts with UTF-8 encoding without BOM in Notepad++?

When saving PHP scripts with UTF-8 encoding without BOM in Notepad++, potential issues can arise with the interpretation of the script by the PHP interpreter. This can lead to unexpected behavior or errors in the script execution. To solve this issue, you can add the following line at the beginning of your PHP script to explicitly specify the UTF-8 encoding:

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