Question

Hello, so i dont use this chat very much so

not sure this is where my question belongs. But out of curiousity... this website (https://www.sql-practice.com/) amongst many others like W3Schools etc... whenever you test stuff like SQL, PHP, HTML, etc codes..... and you get a result back.

I know a basic formular and stuff, but how does (with current website here linked as example) people create websites like these? It must take a lot of work? I'm a developer myself with PHP and SQL... basic stuff really... was pretty good once but trying to get back in the game after many years of doing other stuff (education wise).

And again, pure curiousity. Like this website, in the middle content area where you can write SQL code to test the returns... i see that everytime you have a new line of code, out on the left side you see code-line-numbers and such? How do i make such things? Reason as to why im asking is that im considering making something similar on my own (and only for me), so that i can practise different codes out on my own portfolio online when needed...

sry for bad english, again, been a while but any help or suggestions would be awesome! Many thanks! And if i posted this the wrong place, sry for this and admin may delete this post. Good day :D

You are asking quite a few questions. Only one that has anything to do with databases is about how to run user entered queries safely, which I guess the answer would be to run in a secured sandbox environment. For the UI questions, I guess you need to brush up on your front-end development knowledge.
