What are the best practices for ensuring secure user authentication in PHP applications while utilizing Apache authentication mechanisms?

One of the best practices for ensuring secure user authentication in PHP applications while utilizing Apache authentication mechanisms is to use HTTPS to encrypt the communication between the client and server. This helps prevent eavesdropping and man-in-the-middle attacks. Additionally, storing user passwords securely hashed in a database and using strong password policies can enhance the security of user authentication. 

// Example code snippet for secure user authentication in PHP using Apache authentication mechanisms

// Ensure HTTPS is used for secure communication
if ($_SERVER['HTTPS'] != 'on') {
    header('Location: https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']);
    exit();
}

// Hash and store user passwords securely in the database
$password = password_hash($_POST['password'], PASSWORD_DEFAULT);
// Store $password in the database for user authentication

// Implement strong password policies for user authentication
// For example, require a minimum password length and complexity
