WebSocket IntroductionWebSocket is an important feature of HTML5. It is HTML5 a new protocol that implements browser-to-server full-duplex communication (Full-duplex).

This article mainly introduces the example of using websocket in php. For more information, seeThe following figure shows the handshake between the client and the server when a websocket connection is established.

In the spring consolidation WebSocket Example (above) article, we have implemented the WebSocket, but there is still a core business implementation class is not implemented, here we implement this business core class, because the old couple involved in the system using WebSocket to send messages, So the implementation
Here I draw a diagram demonstrating the handshake part of a websocket connection between the client and the server, which can be done very easily in node, because the net module provided by node has encapsulated the socket socket, and the developer will use only Consider the interaction of the data without dealing with the establishment of the connection. and PHP does not, from the socket connection, establishment, binding, monitoring, etc., these nee
Here I draw a diagram showing the handshake part of the WebSocket connection between the client and the server, which can be done very easily in node, because the net module provided by node has already encapsulated the socket socket, and developers only need to use Consider the interaction of the data without having to deal with the establishment of the connection. and PHP does not, from the socket connection, establishment, binding, monitoring, and

When WebSocket is communicating, it is possible to choose a transmission mode with string or byte stream. However, when sending and receiving, it is necessary to consider the subcontracting of the data, which is divided into request and response messages. No matter which mode of transmission is used, it is unavoidable to encounter this problem.When a string is transferred, the receiving side can stitch together each received string, and then detect wh

what is websocket. WebSocket is a real-time technology for resolving server - side and client communication. Ajax can also communicate, but he can't do it in real time. We want real-time effects before websocket, all through polling, which is obviously a waste of resources. WebSocket's strength is that, compared to Ajax needs to initiate requests from the client
