This article mainly introduces phpsocket programming in a simple way. This article describes socket-related knowledge in detail, and the content of PHP socket programming instances in line, for more information about TCP/IP, UDP, and Socket

Linux Network Programming-what can the original socket do ?, Linux Network Programming Generally, the programmer receives two types of sockets:(1) stream Socket (SOCK_STREAM): a connection-oriented

into three steps: server listening, client request, and connection confirmation. A server listener is a server socket that monitors the network in real time, instead of locating a specific client socket, but waiting for a connection. A client request is a connection request initiated by a client socket. The target is a server

7. UDP In the most common sense, the so-called UDP is a network protocol that does not matter when it is sent out. Therefore, the sending end of UDP programming only needs to send, and the network connection status does not need to be checked. The following example describes how to write UDP and describes each API and Data Type in detail.7.1 UDP broadcast sending program The following is an

. 6666, if you receive a connection request, will receive the request and receive the message sent by the client, the client and the server to establish a connection and send a message.Server-side code:Server-SideClient code:ClientOf course, the above code is very simple, there are many shortcomings, this is just a simple demonstration of the basic function of the socket to use. In fact, no matter how complex the network program is, these basic functi

Programming | The socket class for the asynchronous. NET Framework is actually the managed code version of the socket service provided by the Winsock32 API. Where the socket class provides a rich set of methods and properties for network traffic, in most cases the socket cla

the s receive buffer or the protocol is receiving data, then recv waits until the protocol receives the data. When the protocol takes over the data, the RECV function will copy the data from the receive buffer of S to BUF (note that the data received by the Protocol may be greater than the length of the buf, so in this case a few recv functions are called to copy the data from the receive buffer of S. The recv function is just copy data, the real receive data is the protocol to complete, the RE

Programming first from the principle of the use of Socket Interface network communication, here with the most commonly used C/s mode as an example, first, the server has a process (or multiple processes) in the specified port waiting for customers to connect, service program waiting for customer connection information, once connected, Data can be transmitted acco

The socket mechanism provides two socket option interfaces to control the behavior of sockets. An interface is used to set options, and another interface is used to allow us to request the status of the option. We can get and set three kinds of options. 1. General options that can work on all socket types. 2. Options for managing at the

Linux Socket programming We are well versed in the value of information exchange, so how can we communicate between processes on the network, such as how the browser processes communicate with the web server when we open a browser to browse the web page every day? When you use QQ chat, how does the QQ process communicate with the server or the QQ process where yo
