How to make the web server (Apache) not search for pages at the entered URL, but delegate this task to the router?

Question

PHP

Typically, the router checks the URL against a certain list of available addresses, but if the addresses in the list are not real directories, then the web server returns 404, while I need the router to process the URL, and dynamically create the page.

Answer 1

In the end, I solved it like this:
.htaccess in the root of the site:

RewriteEngine On
RewriteBase /
RewriteRule ^(.*)$ index.php [QSA,L]

and index.php itself handles url requests.

Answer 2

Typically, the router checks the URL against a specific list of available addresses.

What? Was the grass good? The router has nothing to do with urls at all, it works much lower.
