How to make 301 redirect from .html to php via .htaccess?

Question

PHP

In a WordPress blog, all entries (1000+ items) with .html at the end of the URL (for example, test.ru/blog/page.html)

Now you need to make a transition to the PHP page (for example, test.ru/blog/page). This is solved by setting in the admin panel.

But after that, all pages in search engines will return 404. How to make a correct redirect on the entire site so that 301 redirects from .html to without work?

What if you do it stupidly?

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)\.html$ $1 [R=301,L]
