socket operation on non socket

Write your own client programAlso is to achieve the function of the previous article, the client program is no longer using Telnet, their own code implementation, the server-side program needs to be modified under Server programs #include #include #include #include #include #include #include voidErrorChar*MSG) {fprintf(stderr,"%s:%s\n", MSG, strerror (errno));Exit(1);}intOpen_listener_socket (void){ints =

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 programmin

list of functions in this series, see http://www.php.net/manual/en/ref.sockets.php.I think this list is very rich? However, it is a pity that this module is still very young and has many immature places, and there are very few references :(I am also working on it, so I will not discuss it for the moment. I will only give you a reference article. Http://www.zend.com/pecl/tutorials/sockets.php 2. use PHP socket extension Server code: Client code: Sta

characteristic is called the client, the clients mainly connects the remote system and obtains the data;(another behavior in the socket is called server, the server uses the socket to receive the connection and provides the data, and the client is the opposite, so www.baidu.com is an HTTP server, the browser is an HTTP client)# _*_ Encoding:utf-8 _*_import socket
