What alternative solution was suggested by a user in response to the original problem?

Issue: The original problem was that the user was trying to store sensitive information in a PHP file, which is not secure as PHP files can be accessed directly by anyone with the file path. Solution: An alternative solution suggested by a user was to store the sensitive information in a separate configuration file outside of the web root directory. This way, the information is not accessible via a URL and is more secure.

// config.php file outside of web root directory
<?php
define('DB_HOST', 'localhost');
define('DB_USER', 'username');
define('DB_PASS', 'password');
define('DB_NAME', 'database_name');
?>

// index.php file in web root directory
<?php
require_once('../config.php');
// Use the constants defined in config.php for database connection
$conn = new mysqli(DB_HOST, DB_USER, DB_PASS, DB_NAME);
?>
