How to replace %20 in url with -?

Question

PHP

Good afternoon, tell me how to replace the characters% 20 with a dash?
The URL looks like this
site.ru/kazakhstan/Almaty%20Oblysy/Otegen%20Batyr.html /Otegen-Batyr.html but redirected to site.ru/kazakhstan/Almaty%20Oblysy/Otegen%20Batyr.html so as not to remake the database. Is it possible to do in htaccess without 301 redirect. Because there are many countries, regions and cities, or is it possible to do it in some other way?

Answer 1

If you are satisfied with a crutch, and you are not afraid that one day someone will curse you while supporting this project, then simply at the entry point, even before routing, replace "-" with "% 20" (or vice versa, I did not quite understand what exactly what you want).

Answer 2

url_decode()
