What steps should be taken to ensure UTF-8 encoding is properly configured in a PHP project, including database settings?

To ensure UTF-8 encoding is properly configured in a PHP project, including database settings, you need to make sure that your PHP files are saved with UTF-8 encoding, set the correct character set in your HTML meta tags, and configure your database connection to use UTF-8 encoding. 

// Set UTF-8 encoding in PHP files
header('Content-Type: text/html; charset=utf-8');

// Set UTF-8 encoding in HTML meta tags
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

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