Redirect nginx gluing? remove .php?

Question

Nginx

location / {
rewrite ^/(\w+)$ /$1.php;
}

removes .php but let's say if you go to mysite.com/katalog.php then there is no redirect to mysite.com/katalog how to make gluing?

Answer 1

location / {
if (!-e $request_filename){
rewrite ^(.*)$ /$1.php;
}
}
if ($request_uri ~ "\.php") {
rewrite ^/(.+)\.php$ /$1 permanent;
}
it all turned out like a roving

Answer 2

do not rewrite but redirect
gluing can be done by specifying the canonical url
