can not read serial port using php or nodejs - php

Question

I have tried to read serial port data sending with arduino by php or nodejs and I couldn't. I think my codes are correct. I think the problem is permission access reading serial port limited by windows or browser but i'm not sure. although the software of arduino can read data.
when I run my codes, arduio sends data over and over but nothing to show data.
can you help me?!
Here my php codes:
<?php
//-- settings --//
//brainboxes serial ports
$portName = "COM5";
$baudRate = 9600;
$bits = 8;
$spotBit = 1;
header( 'Content-type: text/plain; charset=utf-8' );
?>

exit;
}
try
{
//the serial port resource
$bbSerialPort;
echoFlush( "Connecting to serial port: {$portName}" );
if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN')

$bbSerialPort = dio_open($portName, O_RDWR );
//we're on windows configure com port from command line
exec("mode {$portName} baud={$baudRate} data={$bits} stop={$spotBit} parity=n xon=on");
}
else //'nix
{
$bbSerialPort = dio_open($portName, O_RDWR | O_NOCTTY | O_NONBLOCK );
dio_fcntl($bbSerialPort, F_SETFL, O_SYNC);
//we're on 'nix configure com from php direct io function
dio_tcsetattr($bbSerialPort, array(
'baud' => $baudRate,
'bits' => $bits,
'stop' => $spotBit,
'parity' => 0
));
}
if(!$bbSerialPort)
{
echoFlush( "Could not open Serial port {$portName} ");
exit;
}
// send data
$dataToSend = "HELLO WORLD!";
echoFlush( "Writing to serial port data: \"{$dataToSend}\"" );
$bytesSent = dio_write($bbSerialPort, $dataToSend );
echoFlush( "Sent: {$bytesSent} bytes" );
//date_default_timezone_set ("Europe/London");
$runForSeconds = new DateInterval("PT10S"); //10 seconds
$endTime = (new DateTime())->add($runForSeconds);
echoFlush( "Waiting for {$runForSeconds->format('%S')} seconds to recieve data on serial port" );
while (new DateTime() < $endTime) {
$data = dio_read($bbSerialPort, 256); //this is a blocking call
if ($data) {

Error in php:

Here my nodejs codes:
var express = require('express'),
app = express(),
server = require('http').Server(app),
io = require('socket.io')(server),
port = 8888;
//Server start
server.listen(port, () => console.log('on port' + port))
//user server
app.use(express.static(__dirname + '/public'));
io.on('connection', onConnection);
var connectedSocket = null;
function onConnection(socket){
connectedSocket = socket;
}
//Arduino to CMD
const SerialPort = require('serialport');
const Readline = SerialPort.parsers.Readline;
const usbport = new SerialPort('COM5');
const parser = usbport.pipe(new Readline());
parser.on('data', function (data) {
io.emit('data', { data: data });
});
