What best practices should be followed when saving PHP files to ensure compatibility with UTF-8 encoding?

When saving PHP files to ensure compatibility with UTF-8 encoding, it is important to save the files in UTF-8 format without BOM (Byte Order Mark). This can be achieved by configuring the text editor to save files in UTF-8 without BOM. Additionally, it is recommended to use UTF-8 encoding for all string literals and database connections to avoid encoding issues. 

<?php
// Ensure UTF-8 encoding without BOM
header('Content-Type: text/html; charset=utf-8');

// Set UTF-8 encoding for database connection
$mysqli = new mysqli("localhost", "username", "password", "database");
$mysqli->set_charset("utf8");

// Use UTF-8 encoding for string literals
echo "Hello, 你好, مرحبا";
?>
