I want to programm a simple live chat (with a websocket). (Like that: https://socket-io-chat.now.sh/)
My problem: I only have a normal webserver where I can run php,html.. Not a Node.js server or something like that.
I also have only limited rights [I can't install things,..], because a have rented the server.
If it helps, I have a MYSQL-Database.
Is this possible?
Your stumbing block is likely going to be that you cannot install anything, so Websockets is probably out. You could probably use server sent events to achieve the same sort of result.
Whether you would still describe it as "a simple live chat" once you have finished is another matter.
