In PHP you can use
header function and create 301 redirect.
Here is a sample snippet.
header('Location: http://example.com', true, 301);
The code below is an older version of this post.
header("HTTP/1.1 301 Moved Permanently"); header("Location: [http://example.com](http://example.com)");
This will redirect the PHP page you have added this into
example.com, you can change
example.com to any domain you prefer, you can do the same to file with extensions and subdomain.
Thanks to, Christian Häusler for the tip.
