How to add .php extension with parameter to post URLs in Wordpress?

Question

PHP

Hello! I am transferring the old site from a self-written engine to the Wordpress CMS and faced such a problem that on the old site all the urls look like this:
https://site.ru/page.php?page_id=92
On the new site it is very important for me to keep the same urls, making 301 redirects to new addresses is very There are also external links.
In the settings of permalinks in Wordpress, I did this:
/page.php?id=%post_id%
But it does not work, I get 404 pages.
Please, tell me, can someone already solved this problem?
