If you want to redirect non-www to www domain name then add the following code into the top of every page of the website.
1 2 3 4 5 6 7 | if (substr(getenv('HTTP_HOST'),0,3) != 'www') { header('HTTP/1.1 301 Moved Permanently'); header('Location:http://www.'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']); } |
