How to write a catalog in PHP with SEO optimization?

Question

PHP

Good evening!
Now I am creating a self-written engine for an online store. The question arose of how to implement the catalog: on many sites, the product page is located at the link domen.ru/catalog/company/model/. But if there are more than 100 products, then this is already more than 100 folders, which will be very inconvenient for editing. How to make sure that the necessary urls are transferred to the right place? I was thinking of making it a 404 redirect followed by a php script parsing the url. But wouldn't a 404 on every page be bad for SEO?
Thanks in advance

Answer 1

You need to do the routing in code, not on the web server.
See how to do it right here: symfony.com/doc/current/book/routing.html

Answer 2

Why connect some extra scripts when a person wants to write a self-written engine?
You can do it much easier:
in htaccess something like this is written:
RewriteRule ^([az]{3,20})/([az]{3,20})/([az]{3,20})/$ /index.php?catalog=$1&firm=$2&model=$3
And then in php catch $_GET and pull out what you need
