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:

代码如下:
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");
}
}
}

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:

代码如下:
$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);

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
