What are the potential security risks associated with hardcoding sensitive information like database credentials in PHP scripts?

Hardcoding sensitive information like database credentials in PHP scripts can pose a significant security risk as it exposes this information to potential attackers who may gain unauthorized access to the database. To mitigate this risk, it's recommended to store sensitive information in environment variables or a configuration file outside of the web root directory. 

// Load sensitive information from a configuration file
$config = include('config.php');

// Use the credentials from the configuration file
$servername = $config['servername'];
$username = $config['username'];
$password = $config['password'];
$dbname = $config['dbname'];

// Connect to the database using the credentials
$conn = new mysqli($servername, $username, $password, $dbname);

// Check the connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
