Php与Android socket通信

注：php作为服务端, android作为客户端

Php服务端：

<?php

//确保在连接客户端时不会超时

set_time_limit(0);

//设置IP和端口号

$address='127.0.0.1';

$port=3333; //调试的时候，可以多换端口来测试程序！

//创建一个SOCKET

if(($sock=socket_create(AF_INET,SOCK_STREAM,SOL_TCP))<0)

{

echo "socket_create()失败的原因是:".socket_strerror($sock)."
";

}

//绑定到socket端口

if(($ret=socket_bind($sock,$address,$port))<0)

{

echo "socket_bind()失败的原因是:".socket_strerror($ret)."
";

}

//开始监听

if(($ret=socket_listen($sock,4))<0)

{

echo "socket_listen()失败的原因是:".socket_strerror($ret)."
";

}

do {

if (($msgsock = socket_accept($sock)) < 0)

{

echo "socket_accept() failed: reason: ". socket_strerror($msgsock) . "/n";

echo "/nThe Server is Stop……/n";

break;

}

//发到客户端

$msg ="Welcome ToServer!
";

socket_write($msgsock, $msg, strlen($msg));

socket_close($msgsock);

echo "/nThe Server is running……/n";

printf("/nThe Server is running……/n");

} while (true);

printf("========出来了……/n");

socket_close($sock);

Android客户端:

package com.msi.getwebpage;

import java.io.IOException;

import java.io.InputStream;

import java.io.OutputStream;

import java.net.Socket;

importjava.net.UnknownHostException;

import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

public class SocketTestextends Activity {

/** Called when the activity is firstcreated. */

@Override

public void onCreate(BundlesavedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

try {

System.out.println("准备连接");

Socket socket = new Socket("10.0.2.2",3333);

System.out.println("连接上了");

Intent intent = new Intent();

intent.setClass(SocketTest.this, ConnectActivity.class);

SocketTest.this.startActivity(intent);

InputStream inputStream = socket.getInputStream();

byte buffer[] = new byte[1024*4];

int temp = 0;

String res = null;

//从inputstream中读取客户端所发送的数据

System.out.println("接收到服务器的信息是：");

while ((temp = inputStream.read(buffer)) != -1){

System.out.println(new String(buffer, 0, temp));

res += new String(buffer, 0, temp);

}

System.out.println("已经结束接收信息……");

socket.close();

inputStream.close();

} catch (UnknownHostException e) {

e.printStackTrace();

} catch (IOException e) {

e.printStackTrace();

}
