PHP socket通訊之UDP

標籤：world   cti   recv   bst   ror   date   sub   列印   style   

服務端:

    //伺服器資訊      $server = ‘udp://127.0.0.1:9998‘;      //訊息結束符號      $msg_eof = "\n";      $socket = stream_socket_server($server, $errno, $errstr, STREAM_SERVER_BIND);      if (!$socket) {          die("$errstr ($errno)");      }            do {          //接收用戶端發來的資訊          $inMsg = stream_socket_recvfrom($socket, 1024, 0, $peer);          //服務端列印出相關資訊          echo "Client : $peer\n";          echo "Receive : {$inMsg}";          //給用戶端發送資訊          $outMsg = substr($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);  

用戶端:

function 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;
