How can PHP developers ensure secure data transmission when redirecting users to another page?

To ensure secure data transmission when redirecting users to another page, PHP developers can use HTTPS protocol to encrypt the data being transmitted. This can be achieved by setting up an SSL certificate on the server to enable secure communication between the client and the server.

// Redirect user to another page using HTTPS
header("Location: https://www.example.com/secure-page.php");
exit();
