Oh, I see what you mean. I thought you meant output HTML and templating vs server side logic, but yes, obviously I know the difference as the only front-end language is JavaScript and derivatives.
I’m more used to the terms ‘server-side’ and ‘client-side’ btw. Obviously PHP is server-side. But not all server-side is backend in my view. I consider backend to be application logic and things like database access. Templating can be done on the server or the client, and that’s front-end.
Wow, that was way ahead of its time for 1993. I remember in 1991 or so my dad showing me how he could connect to a library in Italy over the internet, maybe using Gopher or something. My reaction was ‘why tf would we want to do that? Sounds useless’. Not sure why, because in 1984 we had a Commodore 64 game with a big ad for People Link. I asked my mom if we could sign up because chatting with other people through a computer sounded awesome and she told me no, I’d get molested (also very forward-thinking).
