使用wamp时，从wampserver里的php下的php扩展修改打开php_sockets。因为wamp里有两个php.ini，一个在php目录下，一个在apache的bin目录里，手动修改两个都要修改。

socket

1. java：

    ServerSocket serverSocket=new ServerSocket(8888);  
            while(true){  
                Socket socket=serverSocket.accept();  
                BufferedReader br = new BufferedReader(new InputStreamReader(socket.getInputStream()));  
                String line = br.readLine();  
                System.out.println(line);  
                br.close();  
                socket.close();  
                OutputStream out=socket.getOutputStream();  
                out.write("hahaha,try?OK?".getBytes("utf-8"));  
                out.close();  
                socket.close();  
            }  
   

   Socket socket = new Socket("192.168.0.53", 10007); //客户端

2. php：

   <?php  
   
   error_reporting(E_ALL);
   // 建立server端socket  
   $tcp = getprotobyname("tcp");  
   $socket = socket_create(AF_INET, SOCK_STREAM, $tcp); 
   if(($sock=socket_create(AF_INET,SOCK_STREAM,SOL_TCP))<0)
   {
     echo "socket_create() 失败的原因是:".socket_strerror($sock)."<br>";
   } 
   socket_bind($socket, '192.168.0.53', 10007);       //绑定要监听的端口  
   socket_listen($socket);       //监听端口  
   
   //初始化一个数据，和客户端通信  
   $buffer = "connect";  
   while (true) {  
       // 接受一个socket连接  
       $connection = socket_accept($socket);  
       if(!$connection){  
           echo "connect fail";  
       }else{  
           echo "Socket connected\n";  
               // 向客户端传递一个信息数据  
           if ($buffer != "") {  
               echo "send data to client\n";  
               socket_write($connection, $buffer . "\n");  
               echo "Wrote to socket\n";  
           } else {  
               echo "no data in the buffer\n" ;  
           }  
               // 从客户端取得信息  
           while ($data = socket_read($connection, 1024)) { 
               echo ($data); 
               printf("Buffer: " . $data . "\n");  
                       //取得信息给客户端一个反馈  
               //socket_write($connection, "Information Received\n");  
           }  
       }  
   
       socket_close($connection);  
       //关闭 socket  
       printf("Closed the socket\n");  
   }  
   ?>
