What role does SSL certification play in the interaction between a website and social media platforms like Facebook?

SSL certification plays a crucial role in ensuring secure communication between a website and social media platforms like Facebook. Without SSL certification, data transmitted between the website and Facebook can be intercepted by malicious third parties, compromising the security and privacy of users. To ensure secure communication, website owners should obtain an SSL certificate and configure their server to use HTTPS protocol.

// Redirect all incoming traffic to HTTPS
if($_SERVER["HTTPS"] != "on") {
    header("Location: https://" . $_SERVER["HTTP_HOST"] . $_SERVER["REQUEST_URI"]);
    exit();
}
