How to redirect a URL permanently in PHP?
<?php // Permanent 301 Redirect via PHP
header("HTTP/1.1 301 Moved Permanently");
header("Location: http://domain.tld/new/location/");
exit();
?>
The HyperText Transfer Protocol (HTTP) 301 Moved Permanently redirect status response code indicates that the requested resource has been definitively moved to the URL given by the Location headers. A browser redirects to the new URL and search engines update their links to the resource.
