How can you pass parameters in the header Location in PHP to avoid the "Cookie-Lücke" issue when redirecting to another page?

The "Cookie-Lücke" issue refers to a potential security vulnerability where sensitive data is exposed in the URL when using the header Location for redirection in PHP. To avoid this issue, you can pass parameters in the header Location by encoding them using the urlencode() function. This ensures that the parameters are not visible in the URL and are securely passed to the redirected page. 

// Encode parameters using urlencode()
$param1 = urlencode($param1);
$param2 = urlencode($param2);

// Redirect to another page with encoded parameters
header("Location: anotherpage.php?param1=$param1&param2=$param2");
exit();
