How can the proper use of HTTPS encryption enhance the security of PHP login systems and protect sensitive user data?

Using HTTPS encryption in PHP login systems ensures that sensitive user data, such as passwords and personal information, is securely transmitted over the internet. This encryption prevents unauthorized access to this data by encrypting it before sending it over the network. Implementing HTTPS encryption helps protect user privacy and prevents man-in-the-middle attacks. 

// Enable HTTPS encryption in PHP
if ($_SERVER['HTTPS'] !== 'on') {
    $url = 'https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
    header("Location: $url");
    exit();
}
