How to add information to the site without creating an html file for each new page?

Question

Online shopping

Hello. While doing a project at the university to create a site, the question arose: how to add information to the site without creating an html file for each new page? I am essentially creating a site for films and TV shows (ala Kinopoisk), but I did not find the necessary information on how to do this.
Thanks for answers!

Answer 1

1. Upload the goods to the server in the form of XML files

4. Google until you're blue in the face about "registration/authorization"
5. Write a cart script (adding/storing/updating/deleting/clearing)
6. If in PHP, then PHPMailer in the teeth

Ready-made solutions also do not want to use.

And I just wanted to write "WooCommerce".
But I'll still write: WooCommerce.
Well, Bitrix24.
Well, Google would be shaken with such and such a question.
