PHP Java Socket 通信

team470

　　Java写的Nio Socket Server端，需要从PHP写的页面发送命令过去。
　　Java Socket Server主要代码:
　　public static void main(String args[]) {
  System.out.println("Start Server.....");
  try {
   ServerSocket server = new ServerSocket(8083);
   while(true) {
    Socket client = server.accept();
    System.out.println( client.getInetAddress().toString());
    BufferedReader br = new BufferedReader(new InputStreamReader(client.getInputStream()));
    PrintWriter pw = new PrintWriter(client.getOutputStream(),true);
  String m = br.readLine();  \\因为这里调用的是readLine()方法，默认读到\n才执行完毕。所以在PHP客户端传的的值末尾加上\n。 否则代码会停在这一行不往下执行。
    System.out.println("Client Message:" + m);
    System.out.println("Client IP:" + client.getInetAddress().toString());
    pw.write("Hello, I am from Java Server");
    pw.flush();
    pw.close();
    br.close();
    client.close();
    
    
   }
  } catch (IOException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
 }
　　PHP页面发送请求：
　　<?php
$socket = socket_create(AF_INET,SOCK_STREAM,SOL_TCP) or die('Could Not Connect To Socket');
socket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,array("sec"=>1,"usec"=>0));
　　$connect = socket_connect($socket,'10.50.70.195',8083);
$output = iconv("utf-8","gbk","This is From Message\n");
socket_write($socket,$output,strlen($output));
　　//这一行注释  $str = socket_read($socket,1024,PHP_NORMAL_READ); 如果加上PHP_NORMAL_READ, PHP 客户端读不到Server端传回的值。并且报错：[function.socket-read]: unable to read from socket [0]:。。。。
$str = socket_read($socket,1024);
echo $str;
socket_close($socket);
　　?>
