What does 'Backend' mean?

Question

So I just started studying HTML and I'vre read that PHP is 'Backend'. What does that mean? My father said PHP is basically a dynamic HTML but I still don't really understand it lol. Any help is appreciated.

Answer 1

Another way to think about it is server side and client side. Backend code runs on the server where the website is stored. Front end happens in the person-viewing-the-site's, the client, browser.
Php can be used to generate html dynamically. For instance php can talk to a database and get a list of people who belong to a club and then generate the html for an ordered list of those names. Selecting a different club doesn't need a new html page with that list of names hard coded... the php can just ask the database for the new names and the same code generates the new html list.

Rumy I'd love some tips. I'm really getting into all this coding but since I haven't started CSS yet, my codes look quite raw runned, but I'll get there. Thank you so much btw :)

Answer 3
