How should PHP files be saved to ensure proper handling of UTF-8 characters?

When saving PHP files that contain UTF-8 characters, it is important to ensure that the files are encoded in UTF-8 without BOM (Byte Order Mark). This can be done by configuring the text editor or IDE settings to save files in UTF-8 without BOM. Saving PHP files in this format will ensure proper handling of UTF-8 characters in the code. 

<?php
// Ensure that PHP files are saved in UTF-8 without BOM to properly handle UTF-8 characters
// Add this line at the beginning of your PHP file
header('Content-Type: text/html; charset=utf-8');
?>
