PHP和FLASH的socket_shockwaveflash发送socket-优快云博客

本文详细介绍了一种实现Flash客户端与PHP服务端之间Socket通信的方法。通过实例代码演示了如何搭建服务端监听并处理客户端请求的过程，同时展示了如何在Flash中使用XMLSocket进行连接和数据收发。

最近工作闲来无事，于是想到了有不少人为flash的xmlsocket和 php 的socket 多线程通信问题犯愁，经过研究后，测试成功，贴码如下
PHP服务端:

<?php
//监听套接字=>数据读取流
    $port = 8653;
$adr = "172.16.100.136";

    // create a streaming socket, of type TCP/IP
//创建一个数据流，TCP/IP类型
    $sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);

    // set the option to reuse the port
//设置可以重用端口的选项
    socket_set_option($sock, SOL_SOCKET, SO_REUSEADDR, 1);
//设置非阻塞
    socket_set_nonblock($sock);
    // "bind" the socket to the address to "localhost", on port $port
    // so this means that all connections on this port are now our resposibility to send/recv data, disconnect, etc..
//绑定套接字到指定的地址和端口
//而这意味着所有的消息发送/接受,，断开都要通过这个端口的链接
    socket_bind($sock, 0, $port);

    // start listen for connections
//开始侦听链接
    socket_listen($sock);
    // create a list of all the clients that will be connected to us..
    // add the listening socket to this list
//创建一份将连接我们的链接池
//并且将监听套接字也添加到该池子
    $clients = array($sock);
    while (true) {
// create a copy, so $clients doesn't get modified by socket_select()
//创建一份复制，防止链接池不会被socket_select( )改变，因为是引用传入

$newsock = @socket_accept($sock);
if (false === in_array($newsock, $clients) && false !== $newsock) {
   $clients[] = $newsock;
   $data = @socket_read($newsock, 1024, PHP_BINARY_READ);
   $data = trim($data);
   echo $data . "\n";
   if ('<policy-file-request/>' === $data) {
    $msg ="<cross-domain-policy><allow-access-from domain='*' to-ports='*' /></cross-domain-policy>\0";
    socket_write($newsock, $msg, strlen($msg));
    echo "PHP-Auth\n";
   } else {
    socket_getpeername($newsock, $ip);
    echo "New client connected: {$ip}:\n";
    $msg = $data . "\0";
    socket_write($newsock, $msg, strlen($msg));
   }
   continue;
} else {
   $read = $clients;
   // get a list of all the clients that have data to be read from
   // if there are no clients with data, go to next iteration
   //获取一份所有能读取到数据的链接池
   //如果传递过来的链接池没有有数据的，进入下一个循环
   $res = @socket_select($read, $write = NULL, $except = NULL, 0);
   if (false === $res) {
    echo "Client disconnected\n";
    break;
   } else if (0 < $res) {
    foreach ($read as $read_sock) {
     if ($sock !== $read_sock) {
      $data = @socket_read($read_sock, 1024, PHP_BINARY_READ);
      if (false === $data) {
       // remove client for $clients array
       $key = array_search($read_sock, $clients, true);
       unset($clients[$key]);
       //var_dump($read_sock);
       echo "client disconnected.\n";
      } else {
       $data = trim($data);
       if ('' !== $data) {
        //var_dump($clients);
        //var_dump($read);
        //echo "resource:$res\n";
        echo $data . "...\n";
        $msg = $data . "\0";
        socket_write($read_sock, $msg, strlen($msg));
       }
      }
     }
    }
   }
}
    }
    // close the listening socket
//关闭监听套接字
    @socket_close($sock);
?>
