Html with php and database

Question

What codes or lines of codes would you need to be able to create a replica of Sololearn.com such that you could have people send their problems or programming challenges to the page have the system to store the questions get their solutions from others through the comments panel or section of the page and give the answers back to the sender of the programming challenge.

Answer 1

It’s not that difficulty.
If you really want something like sololearn you would need to send the data over http request.

Basically the only thing you need to do with php is mysql.

You could use websockets and server push to push the new challenge to the client
