How to use drag and drop with knockoutJs and php?

I'm trying for several hours, to understand the js file of knockout-binding.
Can you please help me using php to upload it to my sql server?
The following picture shows the layout of drag and drop.
This one shows the php code when the submit button is pressed to upload photos:
<?php
function resizeImage($resourceType,$image_width,$image_height,$resizeWidth,$resizeHeight) {
// $resizeWidth = 100;
// $resizeHeight = 100;
$imageLayer = imagecreatetruecolor($resizeWidth,$resizeHeight);
imagecopyresampled($imageLayer,$resourceType,0,0,0,0,$resizeWidth,$resizeHeight, $image_width,$image_height);
return $imageLayer;
}
session_start();
// *** Include the class
if (isset($_POST['submit'])) {
$newFileName = $_POST['filename'];
if (empty($_POST['filename'])) {
$newFileName = "gallery";
}else {
$newFileName = strtolower(str_replace(" ", "-", $newFileName));
}
$imageTitle = $_POST['filetitle'];
$imageDesc = $_POST['filedesc'];
$file = $_FILES['file'];
$fileName = $file["name"];
$fileType = $file["type"];
$fileTempName = $file["tmp_name"];
$fileError = $file["error"];
$fileSize = $file["size"];
$fileExt = explode(".", $fileName);
$fileActualExt = strtolower(end($fileExt));
$allowed = array("jpg", "jpeg", "png");
if (in_array($fileActualExt, $allowed)){
if ($fileError === 0) {
if ($fileSize < 2000000) {
$imageFullName = $newFileName . "." . uniqid("", true) . "." . $fileActualExt;
$fileDestination = "../img/gallery/" . $imageFullName;
include_once "db_connection.php";
$sql = "SELECT * FROM users;";
$stmt = mysqli_stmt_init($conn);
if (!mysqli_stmt_prepare($stmt, $sql)) {
echo "SQL statement failed";
}else{
mysqli_stmt_execute($stmt);
$result = mysqli_stmt_get_result($stmt);
$rowCount = mysqli_num_rows($result);
$setImageOrder = $rowCount + 1;
$sql = "UPDATE users SET imgFullName =?, orderGallery=? WHERE userId =?;";
if (!mysqli_stmt_prepare($stmt, $sql)) {
echo "SQL statement failed";
} else{
// Image editing
$new_width = 800;
$new_height = 600;
$sourceProperties = getimagesize($fileTempName);
$uploadImageType = $sourceProperties[2];
$sourceImageWidth = $sourceProperties[0];
$sourceImageHeight = $sourceProperties[1];
$session_id = $_SESSION['userId'];
echo $fileDestination;
mysqli_stmt_bind_param($stmt, 'sii', $imageFullName, $setImageOrder, $session_id);
mysqli_stmt_execute($stmt);
echo $fileDestination . "file destination";
echo $fileTempName . "file temp name";
switch ($uploadImageType) {
case IMAGETYPE_JPEG:
$resourceType = imagecreatefromjpeg($fileTempName);
$imageLayer = resizeImage($resourceType,$sourceImageWidth,$sourceImageHeight,$new_width,$new_height);
imagejpeg($imageLayer,$fileDestination);
break;
case IMAGETYPE_GIF:
$resourceType = imagecreatefromgif($fileTempName);
$imageLayer = resizeImage($resourceType,$sourceImageWidth,$sourceImageHeight,$new_width,$new_height);
imagegif($imageLayer,$fileDestination);
break;
case IMAGETYPE_PNG:
$resourceType = imagecreatefrompng($fileTempName);
$imageLayer = resizeImage($resourceType,$sourceImageWidth,$sourceImageHeight,$new_width,$new_height);
imagepng($imageLayer,$fileDestination);
break;
default:
$imageProcess = 0;
break;
}
if ($stmt->error) {
echo "Failure!!! " . $stmt->error;
} else {
// move_uploaded_file($fileTempName, $fileDestination);
}
header("Location: ../putaria.php?upload=success");
}
}
}else {
echo "File size is too big!";
exit();
}
}else {
echo "You had an error!";
exit();
}
}else {
echo "You need to upload a proper file type!";
exit();
}
}
For that code, only works when I press the submit button to upload the pictures.
But in this case, I drop and drag them to the web site, and I want to know how to do it.

Unpack Javascript with PHP

I need a way to unpack JavaScript with PHP the changing code is on my domain here http://beastfeeds.com/ty9.php the full code is in page source view-source:http://beastfeeds.com/ty9.php for some odd reason the webpage only displays part of the code but the full one is there! I just need it to run and decrypt the code so it displays the decrypted code so i can grab the m3u8 from the output as it changes on every page load. Here is what i am trying to run to achieve it which works fine with Javascript Eval (U.n.p.a.c.k.e.d) but not with this format

How to return json string from php array

I am doing something i don't understand how. written a php code in O.O.P and the value gotten from it are objects. but i want to convert this O.O.P object to JSON data to be used in by javascript. so I converted my converted my objects to array on the php end. the try to use the json_encode function on it the script just keep returning errors. so i tried using a function i scope out, it worked but the js keeps on rejecting the data.
Below is the JS file
var ajax = new XMLHttpRequest();
ajax.open('GET','user.php',true);
ajax.setRequestHeader("Content-type","application/json");
ajax.onreadystatechange = function(){
if(ajax.readyState == 4 && ajax.status ==200){
var data = JSON.parse(ajax.responseText.trim());
console.log(data);
console.log(data[username]);
}
}
ajax.send();
it will return this error "SyntaxError: JSON.parse: bad control character in string literal at line 1 column 129 of the JSON data"
without the JSON.parse it return undefind fro the data.username console log. Below is the PHP SCRIPT
//header("Content-type: application/json");
require_once 'core/init.php';
function array2json($arr) {
/*if (function_exists('json_encode')) {
echo "string";
return json_encode($arr);
}*/
$pars = array();
$is_list = false;
$keys = array_keys($arr);
$max_length = count($arr) - 1;
if (($keys[0] == 0) and($keys[$max_length] == $max_length)) {
$is_list = true;
for ($i = 0; $i < count($keys); $i++) {
if ($i != $keys[$i]) {
$is_list = false;
break;
}
}
}
foreach($arr as $key => $value) {
if (is_array($value)) {
if ($is_list) $parts[] = array2json($value);
else $part[] = '"'.$key.
':'.array2json($value);
} else {
$str = '';
if (!$is_list) $str = '"'.$key.
'"'.
':';
if (is_numeric($value)) $str. = $value;
elseif($value === false) $str. = 'false';
elseif($value === true) $str. = 'true';
else $str. = '"'.addslashes($value).
'"';
$parts[] = $str;
}
}
$json = implode(',', $parts);
if ($is_list) return '['.$json.
']';
return '{'.$json.
'}';
}
$user = new User();
$json = array();
if (!$user - > is_LOggedIn()) {
echo "false";
} else {
foreach($user - > data() as $key => $value) {
$json[$key] = $value;
//$json =json_encode($json,JSON_FORCE_OBJECT);
//echo $json;
}
/*$details = '{"'.implode('", "', array_keys($json)).'"';
$data = '"'.implode('" "', $json).'"}';
die($details.' / '.$data);*/
$json = array2json($json);
print $json;
}
PLEASE HELP ME OUT TO SORT THIS ERROR THANK YOU.

You need to set the response headers, and ensure you are not violating CORS:
/*
* Construct Data Structure
*/
$response =
[
'value1',
'value2'
];
/*
* Format Data
*/
$jsonResponse = json_encode ( $response, JSON_PRETTY_PRINT );
/*
* Prepare Response
*/
header('content-type: application/json; charset=UTF-8');
/*
* ONLY if you want/need any domain to be able to access it.
*/
header('Access-Control-Allow-Origin: *');
/*
* Send Response
*/
print_r ( $jsonResponse );
/*
* Return with intended destruction
*/
die;

Just use the json functions json_encode and json_decode to convert arrays into json string or vice versa:
$myArray = array("value1", "value2");
echo json_encode($myArray);

If websocket handshake completes successfully should I see an onopen event in my client?

First if you could tell me if there is something here that is wrong :
client:
var ws = new WebSocket('ws://localhost:9090/websocket_server.php');// ws://echo.websocket.org/echo
console.log(ws);
ws.onopen = function(e) {
console.log("Connection open...", e);
ws.send("Hello WebSocket!");
};
ws.onmessage = function(e) {
if(typeof e.data === "string"){
console.log("String message received", e, e.data);
} else {
console.log("Other message received", e, e.data);
}
};
ws.onerror = function(e) {
console.log("WebSocket Error: " , e);
};
ws.onclose = function(e) {
console.log("Connection closed", e);
};

while ( $line = socket_read($client, 2048, PHP_NORMAL_READ) ) {
$buf .= $line;
if ( strpos($line, 'Sec-WebSocket-Key')!== false ) {
$key = substr($line, 19);
} else
if ( strpos($line, 'User-Agent')!== false ) {
break;
}
}
//echo $buf;
$sha1 = SHA1($key.KEY_SUFFIX, true);
$accept = base64_encode($sha1);

I run the php script in this way:
F:\xampp\php\php -q D:\websocket_server.php
Question:
Suppose if It's all correct, I keep looking at chrome debugger network section and It's pending and I expected that after this process I should see an onopen event in js console,
what is going on? Am I expecting wrong?
Should the connection between sever and client go from 0 state to 1 state after this process or It needs more work to establish an open state?

I found the problems:
mistakes:
1: reading the last character in the line of the sec-websocket-key which made the calculation of the sec-websocket-accpet wrong on line 18
2: Didn't know 2 things about response header : one is that you need to put \r\n at the end of each line not just \n and seccond is that you need to put two \r\n\r\n after the last line of header, it just doesn't work if it's not two. (lines: 30-33)
Now it initiates an onopen event in client.
