What are the security implications of using HTTP redirects for email links in PHP?

Using HTTP redirects for email links in PHP can pose security risks as it can potentially expose sensitive information in the URL parameters. To mitigate this risk, it is recommended to use a server-side script to handle the redirect and ensure that sensitive data is not passed through the URL. 

<?php
// Redirect to a specific URL without passing sensitive data in the URL
$redirectUrl = 'https://example.com';
header('Location: ' . $redirectUrl);
exit;
?>
