what is the algorithm for a chat?

Question

i made a web chat with php in the simple way i have a database with the fields name , message and is very simple using a form to send the message and save the message in the database , and show it using ajax but somebody tould me that is a comments algorithm , not a chat algorithm

Answer 1

Though i don't have much knowledge about it but he is right i guess . This is how comments algorithm might work . Chat can be implemented this way but there will be a large amount of connection opening and closing using something like polling(and any connection takes a good amount of time) and all of it can delay things and lead to bad user experience. You should instead look into websockets to implement this chat system.
