In PHP, what are the implications of using $_GET versus $_POST to retrieve form data for database operations?

When retrieving form data for database operations, it is important to consider the implications of using $_GET versus $_POST. Using $_GET exposes the data in the URL, making it visible to users and potentially insecure for sensitive information. On the other hand, $_POST sends the data in the HTTP request body, keeping it hidden from users and more secure for sensitive information. Therefore, it is recommended to use $_POST for database operations to ensure data security. 

// Using $_POST to retrieve form data for database operations
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST['username'];
    $password = $_POST['password'];
    
    // Perform database operations using the retrieved data
}
