php socket基础原理|服务端server.php|客户端client.php

php socket基础原理，基础使用方法：
服务端：创建一个socket套接字 =》绑定这个socket到指定的IP与端口上 =》监听这个socket的所有链接请求 =》响应或者返回数据
客户端：创建一个socket套接字 =》连接需要请求的socket =》发送数据到socket =》读取socket的响应数据

(~_~)理解不当之处还请同学修正~~~

1. Server.php
4. $host = '192.168.0.10';
5. $port = 88888;
7. if($socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)){
8. echo "socket create success.\n";
9. }
11. if($bind = socket_bind($socket, $host, $port)){
12. echo "socket bind success.\n";
13. }
15. if($listen = socket_listen($socket)){
16. echo "socket listening...\n";
17. }
19. if($connect = socket_accept($socket)){
20. echo "socket accept a connect success.\n";
21. }
23. //===================================================//
24. socket_write($connect, 'I am from Server.php at DateTime:'.date('Y-m-d H:i:s')."\n");
25. //====================发送到客户端==================================================//
27. //==================================================//
28. $read = socket_read($connect, 1024);
29. echo $read;
30. //============接受客户端过来的消息============================//
33. //while($connect= socket_accept($socket)){
34. // $read = socket_read($connect, 1024);
35. // echo $read;
36. //}
37. //循环accept
