How can you ensure data security when using both POST and GET methods in PHP scripts?

When using both POST and GET methods in PHP scripts, you can ensure data security by validating and sanitizing all input data to prevent SQL injection and other security vulnerabilities. Additionally, you can use SSL encryption to secure data transmission between the client and server. 

// Validate and sanitize input data
$username = isset($_POST['username']) ? htmlspecialchars($_POST['username']) : '';
$password = isset($_POST['password']) ? htmlspecialchars($_POST['password']) : '';

// Use SSL encryption for secure data transmission
if (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off') {
    // Data transmission is secure
} else {
    // Redirect to HTTPS version of the page
    header('Location: https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']);
    exit();
}
