What are some best practices for handling redirects in PHP to ensure optimal user experience?

When handling redirects in PHP, it is important to ensure that the user experience is optimal by using HTTP status codes correctly, providing clear and informative messages, and avoiding unnecessary redirects. One best practice is to use a 301 redirect for permanent redirects and a 302 redirect for temporary redirects.

// Redirect to a new page using a 301 status code for permanent redirect
header("HTTP/1.1 301 Moved Permanently");
header("Location: http://www.example.com/new-page");
exit;

// Redirect to a temporary page using a 302 status code for temporary redirect
header("HTTP/1.1 302 Found");
header("Location: http://www.example.com/temp-page");
exit;
