PHP Socket Programming Process detailed Introduced Sockets are used for interprocess communication. Interprocess communication is typically based on a client-server model. At this point, the client-server is an application that can interact with each other. The interaction between the client and the server requires a connection. Socket programming is responsible for establishing an interactive connection

) to connect a serversocket (S), so wrote two simple programs and analysis, features a dataacceptserver, You can create 4444 ports, can accept up to 50 connections, two Datasender, create long connections, and know how to send Byebye. For convenience, use UTF-8 character streams. The procedure is as follows://server Importjava.io.BufferedReader; Importjava.io.IOException; Importjava.io.InputStreamReader; Importjava.io.OutputStreamWriter; Importjava.io.PrintWriter; Importjava.net.ServerSocket; Im

Hidden trouble 1. Ignore return statusThe first pitfall is obvious, but it's the easiest mistake for a novice developer to make. If you ignore the return state of a function, you may get lost when they fail or partially succeed. This, in turn, can spread errors, making it difficult to locate the source of the problem.Captures and checks each return state, rather than ignoring them. Consider the example shown in Listing 1, a socket send function.Listin

calls return immediately.In addition, in many cases, Socket programming is implemented on the client and server based on different situations, and the application program is compiled on the client to send requests to the specified port on the server, at the same time, the preparation of the server application to process the request has been mentioned in the above description; of course, not all Socket prog

we introduce the process of the four handshake release connection in the socket, please look at the following figure: Figure 2 TCP Four-time handshake sent in socket The diagram process is as follows: An application process first calls close to actively shut down the connection, at which point TCP sends a FIN M; The other end receives the fin m and performs a passive shutdown to confirm the f

Introduced The socket is used for interprocess communication. Interprocess communication is typically based on the client-server side model. At this point, the client-server side is an application that can interact with one another. The interaction between the client and the server needs to be connected. Socket programming is responsible for establishing an interactive connection between applications. In

in the form. "|" in the string The previous sections are specific commands, including Conn, CHAT, PRIV, gone four types. The conn command creates a new client connection, sends an existing list of users to a new user and informs other users that a new user is joining. The chat command sends new information to all users. The Priv command sends a WHISPER message to a user. The Gone command removes a left user from the list of users and informs other users that So-and-so has left. At the same time

connection, when TCP sends a FIN M; After the other end receives fin m, perform a passive shutdown to confirm the fin. Its reception is also passed as a file terminator to the application process, because the receive of fin means that the application process can no longer receive additional data on the corresponding connection; After some time, the application process that receives the file terminator calls close to close its socket.
