demo实现的简单功能是，接受
复制代码 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……
复制代码 代码如下:
$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,
echo $str;
//关闭
socket_close($socket);
先运行起java的服务端，然后用浏览器访问
