Php uses websocket to build a simple chat room and phpwebsocket This example describes how to set up a simple chat room in php Based on websocket. Share it with you for your reference. The details are as follows:1. Preface There is a simple chat room in the company's game. After learning about it, I learned that it was implemented by node + websocket. I think php

/Response mode.The answer is given in the new generation of HTML standard HTML5, which provides a network technology WebSocket for full-duplex communication between browsers and servers. From the WebSocket draft, WebSocket is a completely new, independent protocol, based on the TCP protocol, which is compatible with the HTTP protocol and does not fit into the HTT

PrefaceAs a next-generation WEB standard, HTML5 has a number of compelling new features, such as Canvas, local storage, multimedia programming interfaces, WebSocket, and more. The WebSocket, which has the "Web TCP" , is particularly appealing to developers. The advent of WebSocket makes it possible for the browser to provide support for sockets, providing a two-w

WebSocket protocol is a new protocol for HTML5. It implements browser-to-server full-duplex communication (Full-duplex).Browsers and servers only need to do a handshake, and then a fast channel is formed between the browser and the server. The data can be transmitted to each other directly between the two. In this WebSocket agreement, there are two major benefits to our Instant service: 1. Headers that comm

One: OverviewAs one of the new features of HTML5 websocket components, in the real-time requirements of the Web application development is still a certain use, the high version of IE, Chrome, FF browser support WebSocket, The standard WebSocket communication is based on the RFC6455 implementation of the server-side handshake with the client and the message. If th

We have introduced WebRTC and read the example of https://apprtc.appspot.com/on the Internet (which may need to be accessed through a wall). This example is an application deployed on the Google App Engine and relies on the Gae environment, the background language is Python and also relies on the Google App Engine channel API. Therefore, it cannot be run locally or be expanded. After studying the Python source code in the example, I decided to implement it in Java. After Tomcat 7, I started to s

The distribution of Message Centers is achieved through establishing a persistent connection between websocket and the backend server. The advantage of this method is to save network bandwidth, second, users can receive messages sent from the backend in real time. netty is used in the backend implementation. After stress testing, each server can withstand 0.5 million persistent connections, that is, 0.5 million users at the same time (only one persist

WebSocket is a simple demo program based on javaweb + tomcat, and websocketjavaweb As required by the project, after the frontend initiates a request to the background, the background must be divided into multiple steps for relevant operations, and the time required for completing each step cannot be determined. If ajax is used to repeatedly access the background to obtain real-time data, it is obviously not suitable, whether it is a waste of resource

WebSocket initiates a single request, the server does not need to wait for the customer service side, the client at any time can also send messages to the service side, reduce the polling time delay. After a connection has been made, it can be sent multiple times to the client. Is the difference between polling and WebSocket.HTTP-based real-time messages are quite complex, maintaining a state of call in a stateless request adds complexity, and cross-d

HTML5 has many notable new features, such as Canvas, local storage, multimedia programming interfaces, WebSocket, and so on. Although everyone is very enthusiastic about it, I personally think it requires the support of other platforms to truly "fire ". I used to explain in detail other methods such as ajax-based "polling" and "long polling" during web communication. Round robin: This is the earliest solution to implement real-time Web applications.

Transferred from: http://www.cnblogs.com/hsxixi/archive/2011/12/24/2300641.htmlFrom this time on, let's set up a simple chat room. Because the HTTP protocol is stateless, building a chat room like this has never felt gegedada is not so logical. If you do not use the flash, applets and other browser plug-ins, we need to periodically poll the server to get everyone's chat information. This creates a certain amount of latency and a lot of network traffic.But as HTML5 emerges, the situation is expec

What is WebSocket?WebSocket a protocol for full-duplex communication on a single TCP connection. The WebSocket communication protocol was established as standard RFC 6455 by the IETF in 2011 and was supplemented by RFC7936, WEBSOCKETAPI by the network.WebSocket is a standalone protocol that is created on TCP, and the only association to HTTP is a protocol switch

First, WebSocket Overview The WebSocket protocol is based on the TCP protocol, not the HTTP protocol.As follows:ws://127.0.0.1 or wss://127.0.0.1 is the websocket request.Note: ws represents WebSocket protocol, WSS represents an encrypted WebSocket agreement. The
