Почему программа пишет в Socket Empty?

Я делаю программу, которая записывает видео и отправляет свои BLOB-объекты в сокет каждые 5 секунд. Кажется, это работает правильно, но когда я смотрю на файлы, полученные сервером, я вижу, что все программы, написанные клиентом сокета, пусты = 0 КБ. Не могли бы вы мне помочь? Мои коды HTML / JS и PHP приведены ниже.

И PHP Socket Client ниже:

<?php

$portnum = 'portnum';
$ipnum = 'Ipnum';

// No Timeout
set_time_limit(0);

if ( ($socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) == FALSE ) {
$message = "Socket not created";
echo "<script type='text/javascript'>alert('$message');</script>";
}$context = stream_context_create($opts);
if ( ($file = file_get_contents($_FILES['blob'], false, $context ) )  == FALSE ) {
$message = "File_get_contents not working.";
echo "<script type='text/javascript'>alert('$message');</script>";
}
$ss = fopen ( file, "r");
$streamvid = fread ( $ss );if ( ( $tt = fsockopen($ipnum, $portnum, $errno, $errstr, 30)) == FALSE ) {

Решение

mediaRecorder.ondataavailable = function(blob) {
// upload blob to PHP server
uploadToPHPServer(blob);
};

function uploadToPHPServer(blob) {
var file = new File([blob], 'msr-' + (new Date).toISOString().replace(/:|\./g, '-') + '.webm', {
type: 'video/webm'
});

// create FormData
var formData = new FormData();
formData.append('video-filename', file.name);
formData.append('video-blob', file);

makeXMLHttpRequest('https://path-to-your-server/save.php', formData, function() {
var downloadURL = 'https://path-to-your-server/uploads/' + file.name;
console.log('File uploaded to this path:', downloadURL);
});
}

function makeXMLHttpRequest(url, data, callback) {
var request = new XMLHttpRequest();
request.onreadystatechange = function() {
if (request.readyState == 4 && request.status == 200) {
callback();
}
};
request.open('POST', url);
request.send(data);
}

Вот save.php:

<?php
// via: https://github.com/muaz-khan/RecordRTC/blob/master/RecordRTC-to-PHP/save.php
header("Access-Control-Allow-Origin: *");
function selfInvoker()
{
if (!isset($_POST['audio-filename']) && !isset($_POST['video-filename'])) {
echo 'PermissionDeniedError';
return;
}

$fileName = '';
$tempName = '';

if (isset($_POST['audio-filename'])) {
$fileName = $_POST['audio-filename'];
$tempName = $_FILES['audio-blob']['tmp_name'];
} else {
$fileName = $_POST['video-filename'];
$tempName = $_FILES['video-blob']['tmp_name'];
}

if (empty($fileName) || empty($tempName)) {
echo 'PermissionDeniedError';
return;
}
$filePath = 'uploads/' . $fileName;

// make sure that one can upload only allowed audio/video files
$allowed = array(
'webm',
'wav',
'mp4',
'mp3',
'ogg'
);
$extension = pathinfo($filePath, PATHINFO_EXTENSION);
if (!$extension || empty($extension) || !in_array($extension, $allowed)) {
echo 'PermissionDeniedError';
continue;
}

if (!move_uploaded_file($tempName, $filePath)) {
echo ('Problem saving file.');
return;
}

echo ($filePath);
}
selfInvoker();
?>

Что касается проблем с загрузкой PHP,

PS. Не забудьте создать uploads каталог здесь:
