How can PHP developers effectively handle user authentication and authorization processes to enhance overall system security and user privacy?

To effectively handle user authentication and authorization processes in PHP, developers can use secure hashing algorithms like bcrypt to store passwords, implement role-based access control for authorization, and use HTTPS to encrypt data transmission. By following these best practices, developers can enhance overall system security and protect user privacy. 

// Example code for user authentication using bcrypt hashing
$password = 'user_password';
$hashed_password = password_hash($password, PASSWORD_BCRYPT);

// Example code for role-based access control
$user_role = 'admin';
if($user_role == 'admin'){
    // Allow access to admin-only content
} else {
    // Redirect or deny access
}

// Example code for encrypting data transmission with HTTPS
// Ensure that your server is configured to use HTTPS for secure communication
