I am changing the layout of a website born in 2005. I have html and php pages that I have to redirect.
I am writing the follow php code:
<?
Header( "HTTP/1.1 301 Moved Permanently" );
Header( "Location: http://www.example.com/new-page/" );
?>

I am not able to edit .htaccess, so I wonder if (from a Google point of view) a php redirect by php is accepted.
My doubt is that Google help does not mention any php redirect, but only .htaccess.
