php与java通过socket通信的实现代码

　　import java.io.*;

　　import java.net.*;

　　public class Server {

　　public static void main(String[] args) throws IOException{

　　System.out.println("Server started !\n");

　　ServerSocket server=new ServerSocket(5678);

　　while (true){

　　Socket client=server.accept();

　　System.out.println("client coming!\n");

　　PrintWriter printer = new PrintWriter(client.getOutputStream());

　　BufferedReader reader = new BufferedReader(new InputStreamReader(client.getInputStream()));

　　String  m = reader.readLine();

　　System.out.println("get infomation " + m + "\n from " + client.getInetAddress().toString());

　　printer.println(m);

　　printer.flush();

　　printer.close();

　　printer.close();

　　client.close();

　　System.out.println("client leaving!\n");

　　}

　　}

　　}

　　<?php

　　$socket = socket_create ( AF_INET, SOCK_STREAM, SOL_TCP ) or die ( 'could not create socket' );

　　$connect = socket_connect ( $socket, '127.0.0.1', 5678 );

　　//向服务端发送数据

　　socket_write ( $socket, 'Hello' . "\n" );

　　//接受服务端返回数据

　　$str = socket_read ( $socket, 1024, PHP_NORMAL_READ );

　　echo $str;

　　//关闭

　　socket_close($socket);
