301 redirect in .htaccess after site transfer?

Question

Search Engine Optimization

Tell me, please, who knows
how to solve the problem, the site flew on WordPress, and the pages have seo-weight
cannot be restored. Now everything is on bare html, and there each page ends with .php.
We need a redirect from a page like www.site.ru/mmm/ttt
to a page like www.site.ru/ttt.php
Or, as an option, create a page like www on
html
. site.ru/mmm/ttt

Answer 1

www.site.ru/mmm/tttone-of-a-kind links of the form www.site.ru/mmm/ttt/index.php(well, or whatever you have by default)
.htaccess
RewriteRule ^mmm/(.*)$ $1.php

Answer 2

if the pages have weight, then you need to set them as they are, the redirect does not transfer the entire weight, but only a part. So if it doesn't bother you personally, it's better to keep the urls.
