php与java通过socket通信的实现代码_php实例

demo实现的简单功能是，接受PHP端写入的字符串，然后原样返回给输出端。代码如下：

import java.io.*; <BR>import java.net.*; <br><br>public class Server { <BR>public static void main(String[] args) throws IOException{ <BR>  System.out.println("Server started !\n"); <BR>  ServerSocket server=new ServerSocket(5678); <BR>  while (true){ <BR>                Socket client=server.accept(); <BR>                System.out.println("client coming!\n"); <BR>                PrintWriter printer = new PrintWriter(client.getOutputStream()); <BR>                BufferedReader reader = new BufferedReader(new InputStreamReader(client.getInputStream())); <BR>                String  m = reader.readLine(); <BR>                System.out.println("get infomation " + m + "\n from " + client.getInetAddress().toString()); <BR>                printer.println(m); <BR>                printer.flush(); <BR>                printer.close(); <BR>                printer.close(); <BR>                client.close(); <BR>                System.out.println("client leaving!\n"); <BR>              } <BR>        } <BR>}<BR>

运行起来，以后该java程序将监听5678端口，当接收到消息以后，将接收的消息原样返回给客户端……
PHP的代码如下：

<?php <BR>    $socket = socket_create ( AF_INET, SOCK_STREAM, SOL_TCP ) or die ( 'could not create socket' ); <BR>    $connect = socket_connect ( $socket, '127.0.0.1', 5678 ); <BR>    //向服务端发送数据 <BR>    socket_write (<div style="color:transparent">！本文来源gaodai.ma#com搞##代!^码网(</div><sup>搞gaodaima代码</sup> $socket, 'Hello' . "\n" ); <BR>    //接受服务端返回数据 <BR>    $str = socket_read ( $socket, 1024, PHP_NORMAL_READ ); <br><br>    echo $str; <BR>    //关闭 <BR>    socket_close($socket);<BR>

PHP程序连接本机的5678端口，写入 Hello，然后读取返回的数据……将返回的数据，输出到浏览器……
先运行起java的服务端，然后用浏览器访问PHP页面，将看到从服务器端返回的Hello
