PHP的Socket通信之UDP通信实例

  本文实例讲述了PHP的Socket通信之UDP通信方法。分享给大家供大家参考。具体如下:

  1.创建一简单的UDP服务器

  ?

  18//服务器信息

  $server = 'udp://127.0.0.1:9998';

  //消息结束符号

  $msg_eof = "\n";

  $socket = stream_socket_server($server, $errno, $errstr, STREAM_SERVER_BIND);

  if (!$socket) {

  die("$errstr ($errno)");

  }

  do {

  //接收客户端发来的信息

  $inMsg = stream_socket_recvfrom($socket, 1024, 0, $peer);

  //服务端打印出相关信息

  echo "Client : $peer\n";

  echo "Receive : {$inMsg}";

  //给客户端发送信息

  $outMsg = substr($inMsg, 0, (strrpos($inMsg, $msg_eof))).' -- '.date("D M j H:i:s Y\r\n");

  stream_socket_sendto($socket, $outMsg, 0, $peer);

  } while ($inMsg !== false);

  2.简单的客户端

  ?

  12function udpGet($sendMsg = '', $ip = '127.0.0.1', $port = '9998'){

  $handle = stream_socket_client("udp://{$ip}:{$port}", $errno, $errstr);

  if( !$handle ){

  die("ERROR: {$errno} - {$errstr}\n");

  }

  fwrite($handle, $sendMsg."\n");

  $result = fread($handle, 1024);

  fclose($handle);

  return $result;

  }

  $result = udpGet('Hello World');

  echo $result;

 

  希望本文所述对大家的php程序设计有所帮助。
