How to issue another file on request?

Question

PHP

Request to the browser: https://address/category/category-name/
We will not have a category folder and subfolders for each category on the server.
In which direction to look for information, or some primitive code example.
Tried searching on Google, but couldn't find anything.
Thanks

Stupidly redirect from the old place to the new one - if you have apache then in .htaccess, if only nginx or litespeed then in it.
Google 301 redirect :)

Answer 3

apache - mod_rewrite directive
