This article to share the content is about PHP implementation of System programming network socket and IO multiplexing, has a certain reference value, the need for friends can refer to All along, PHP is rarely used for socket programming, after all, is a scripting language, efficiency will become a big bottleneck, but can not say that PHP can not be used for

Nodejs implements chat rooms based on socket. io Because the socket. io module is used for the web video Live project to be implemented later, I spent some time studying it and made some improvements by referring to the online code. I wrote a chat room code myself. I have to admit that the backend fact push capability

Use node. js + socket. io + redis to implement basic chat room scenarios This article introduces the basic operations of Redis and Redis-cli in the redis database and its basic operations. among them, the publish-subscribe mechanism is widely used, so we will use nodejs to implement this mechanism. this article describes how to use socket in the previous article.

{alert ('The browser does not support WebSocket ~ ');} Currently, browsers such as chrome and firefox support websocket, but IE does not. Next, let's briefly talk about the server's support for websocket. The server supports many websocket languages and has related open-source projects, such as php phpwebsockets: http://code.google.com/p/phpwebsockets/, Java's jwebsocket:http://jwebsocket.org /.For more information, see this article: Start Using HTML5 WebSockets Today.Socket.

Session is required for some authentication in the nodejs project. For example, the demo of the nodejs chat room I wrote is the authentication implemented through session. If a session exists, you can directly log on to the chat room without logging on again. I also found many session calling methods in the Express framework on the Internet, but I found that not many of them are actually usable. Today, based on the production process of the chat room, I sorted out Express and

or an application that requires frequent short-term interaction with services as frequently as Twitter, you may want to 'invert 'the traditional interaction model. therefore, it is better to have the server send data to you than send a request to the server. Today, when we develop a system similar to real-time, we always think of persistent connections, and comet certainly has websocket. however, they have their own limitations. For example, server implementation is different, there are too m

The socket. io client is very elegant in event processing, which is similar to weboscket's limited javascript interface, but supports more custom events: Var socket = io. connect ('HTTP: // localhost: 9000/chat '); Socket. on ('

Use socket. io in node. js to create a namespace. If developers want to completely control the sending of messages and events in a specific application, they only need to use a default "/" namespace. however, if developers need to provide applications to other applications as third-party services, they need to define an independent namespace for a socket port use

Introduction to websocket and other Reverse ajax Technologies In real-time web applications, a common method is reverse Ajax. Definition of reverse Ajax: Reverse Ajax (Reverse Ajax) is essentially a concept that can send data from the server to the client. In a standard HTTP Ajax request, data is sent to the server. Reverse Ajax can simulate an Ajax request in some specific ways, which will be discussed in this article, the server can send events (low-latency communication) to the client as quic

At present, there is a need to connect to the socket. io server of the other party, then receive and store the data. However, no connection code is found for the socket. io client of the php version. Only the connection code of the server is found. Therefore, a client connec
