This paper introduces the design principles and database technology of instant messaging system. This paper also introduces the security problems and common strategies that can be encountered in the design of instant communication system. A model based on instant communication system in common, and are discussed in detail the design of network chat room system, the requirement analysis and design based on Internet chatrooms, through the front end joint development to achieve network chatroom. After the completion of the design, this paper also tested the function and performance of the network chat room, to ensure that the network chatroom can work.This paper mainly based on PHP+Swoole online chat room needs analysis, including user login, registration, network chat, chat log, modify password.
