PHP Socket实现websocket（二）Socket函数

PHP socket函数是调用系统的的Socket函数，可以参考C语言的socket函数。

Socket函数：http://php.net/manual/en/book.sockets.php 

服务器端： 

 <?php

    //设置脚本运行时间不限制

    set_time_limit(0);
    $server_socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
    socket_bind($server_socket, '127.0.0.1', '1212');
    socket_listen($server_socket, 4);

    //设置非阻塞模式
    socket_set_nonblock($server_socket);
    do{

        //当有连接时读入数据，并返回
        $msg_socket = socket_accept($server_socket);
        if($msg_socket)
        {
            $buff = socket_read($msg_socket, 1024);
            echo "client: ".$buff;
            socket_write($msg_socket, $buff);
            socket_close($msg_socket);
        }
    }while(true);

    socket_close($server_socket);

 客户端：

  1 <?php 

 2     set_time_limit(0);
 3     $client_socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
 4     socket_connect($client_socket, '127.0.0.1', 1212);
 5     if(isset($argv[1]))
 6     {
 7         $send = 'client value '.$argv[1];
 8     }
 9     else 
10     {
11         $send = "default";
12     }
13     socket_write($client_socket, $send."
");
14     $response = socket_read($client_socket, 1024);
15     echo "server: ".$response;
16     socket_close($client_socket);

 分别在CLI模式下运行后如图所示：
