Redirect 302 /en/php/index.php http://www.example.com/newpage.html
Note: A 301 redirect means that the page has permanently moved to a new location. A 302 redirect means that the move is only temporary. Search engines need to figure out whether to keep the old page, or replace it with the one found at the new location. So, if your link has changed permanently then go for 301 redirect else go for a 302 redirect.
