How can the use of Notepad++ impact the compatibility of PHP files with UTF-8 encoding?

When working with PHP files in Notepad++, it is important to ensure that the files are saved with UTF-8 encoding without BOM (Byte Order Mark) to maintain compatibility. To do this, simply go to the Encoding menu in Notepad++ and select UTF-8 without BOM before saving the file.

<?php
// PHP code snippet to ensure UTF-8 encoding without BOM
header('Content-Type: text/html; charset=utf-8');
?>
