What are the best practices for securing config.php in a PHP project to prevent data exposure?

To prevent data exposure in a PHP project, it is crucial to secure the config.php file that contains sensitive information such as database credentials. One common practice is to move the config.php file outside of the web root directory to prevent direct access by unauthorized users. Additionally, you can use file permissions to restrict access to the config.php file and encrypt sensitive data within the file for an added layer of security. 

<?php
// Place this code in your config.php file

// Define sensitive information
define('DB_HOST', 'localhost');
define('DB_USER', 'username');
define('DB_PASS', 'password');
define('DB_NAME', 'database');

// Encrypt sensitive data
define('ENCRYPTED_DB_PASS', 'encrypted_password_here');
