PHP development with a Mac socket, but directly in the Socket--blind directly lost, ask the big God solution

socketphp

The relevant code is as follows, $socket =socket_create (Af_inet,sock_stream, $commonProtocol)

or die("cannot create socket\n");  //绑定socket到端口  $result=socket_bind($socket,$host,$port) or die("cannot bind port to socket\n"); //开始监听这个端口  $result=socket_listen($socket,4) or die("could not set up socket listen\n");  //接受连接，另一个socket来处理通信  $msgsock=socket_accept($socket) or die("cannot accept incoming connection\n");  if($msgsock){      echo date("Y-m-d H:i:s D a");  }  //读取客户端发送过来的信息  $input=socket_read($msgsock,1024) or die("cannot read input\n");  $input=trim($input);  $output=strrev($input)."顺序反过来了吧\n";  //对接收到的信息进行处理，然后返回到客户端  socket_write($msgsock,$output,strlen($output)) or die("cannot write");  //关闭socket连接  socket_close($msgsock);  socket_close($socket);  

Show cannot bind port to socket directly on the webpage, please explain!
