Question

I am planning to make a real time messanger app, can you please tell me how can is send a message to my friend or on any other device? Can i do it using PHP?
Do i have to use sql ?

Answer 1

You need sql only if you want to make user Accounts and save the chats, but if you only want to send messages between two clients, that is possible.
