API receiving Half Data

I have a PHP API but when I send data to it using a post or get request the API receives half data, I don't know what the issue is. this same API works on the localhost but gives error on the Public server.
API sendrequset URL:
https://peer.infusiblecoder.com/android/loanapp/sendrequesttoperson.php?request_is_seen=hjhj&loan_request_code=100&req_status=hjh&request_sender_user_name=ghjgjh&request_reciver_user_name=hjhjh&request_sender_user_id=jkjkj&request_reciver_user_id=hjhj&request_time_stamp=ghhgjhh

it gives this result

The problem is $_GET["$req_status_db"]
It should be $_GET["req_status_db"]
You will have to remove $ from all the $_GET keys.
Also, you do not have req_status_db as query param in the URL you have shared.

JSON_encode not outputting anything

I want to send a query result from one php file to my javascript, I've used an AJAX which seems to work as it is getting data from my BaseClass.php. However when using JSON_encode, it is not outputting anything at all. So I can't work out how to send a query result from one php file(MySQLDao.php) to my BaseClass.php so I am then able to send it to my Javascript file.
My Code:
BaseClass.php:
<?php
error_reporting(E_ALL); ini_set('display_errors', 1);
require("Conn.php");
require("MySQLDao.php");
//$param=$_REQUEST['action'];
//echo json_encode($_GET);
//echo var_dump(json_encode($_GET));
$handle = fopen("php://input", "rb");
$param = $_REQUEST['action'];
while (!feof($handle)) {
$param .= fread($handle, 8192);
}
fclose($handle);
if (empty($param))
{
$returnValue["status"] = false;
$returnValue["title"] = "Error";
$returnValue["message"] = "No Data Recieved paige" .$param ."...";
echo json_encode($returnValue);
return;
}
else
{
$dao = new MySQLDao();
if ($dao->openConnection() == false)
{
$returnValue["status"] = false;
$returnValue["title"] = "Error";
$returnValue["message"] = "Connection Could Not Be Established Between Server And Database";
ob_clean();
echo json_encode($returnValue);
}
else
{
//Decodes data, dont change
$body = json_decode($param, true);
$recieved = $body["data"];
//Gets the result of a query
$result = $dao->getResults($recieved);
}
$dao->closeConnection();
//Return the result of the query
ob_clean();
echo json_encode("param" .$param);
echo json_encode("body" .$body);
echo json_encode("recieved" .$recieved);
echo json_encode("result" .$result);
exit();
}
?>
output for the above echo statements:
"paramgetResults""body""recieved""result"
MySQLDao.php - this file holds the query result that I want to pass to my js
<?php
error_reporting(E_ALL); ini_set('display_errors', 1);
//Class for holding queries
class MySQLDao
{
var $dbhost = null;
var $dbuser = null;
var $dbpass = null;
var $mysqli = null;
var $dbname = null;
var $result = null;
//constructor
function __construct()
{
$this->dbhost = Conn::$dbhost;
$this->dbuser = Conn::$dbuser;
$this->dbpass = Conn::$dbpass;
$this->dbname = Conn::$dbname;
}
//Attempt a connection to the database
public function openConnection()
{
//Try and connect to the database
$this->mysqli = new mysqli($this->dbhost, $this->dbuser, $this->dbpass, $this->dbname);
//If the connection threw an error, report it
if (mysqli_connect_errno())
{
return false;
}
else
{
return true;
}
}
//Get method for retrieving the database conection
public function getConnection()
{
return $this->mysqli;
}
//Close the connection to the database
public function closeConnection()
{
//If there is a connection to the database then close it
if ($this->mysqli != null)
$this->mysqli->close();
}
//-----------------------------------QUERY METHODS-------------------------------------
public function getResults()
{
$sql = "SELECT room.room_description FROM room WHERE room.room_id = 1";
$result = $this->mysqli->query($sql);
//if (mysql_num_rows($result) == 1) {
// $obj = mysql_fetch_object($result, 'obResults');
// echo($obj);
// return $obj;
//}
echo json_encode($result);
//echo($result);
//return false;
}
}
?>
My AJAX code in my js file:
$.ajax ({
type: "GET",
datatype: "application/json",
url: "BaseClass.php",
data: { action : 'getResults' },
//error: function(err){console.log(err)},
success: function(output) {
console.log(output);
//alert(output);
}
//error, function(err){console.log(err)}
});
Any help is appreciated thanks!

Alert message not working using php

I was trying to code where whenever I hit the submit button it will show an alert message when there's no data fetch. Can anyone help me?
if(isset($_POST['submitEstatus'])) {
if($_POST['empValue'] == $valEmp AND $_POST['ageValue'] == $valAge AND $_POST['genValue'] == $valGen){
$query = "SELECT * FROM users $valEmp $valAge $valGen";
$result = mysql_query($query);
if ($result = 0) {
$message = "No Data";
echo "<script type='text/javascript'>alert('$message');</script>";
} else {
while($row = mysql_fetch_array($result)){
$lat = $row['lat'];
$lon = $row['lon'];
$fname = $row['fname'];
$address = $row['address'];
echo("addMarker($lat, $lon, '<b>$fname</b><br />$address');\n");
$ageSelected = $valAge;
$empSelected = $valEmp;
$genSelected = $valGen;
}
}
}
I have this error:
mysql_fetch_array() expects parameter 1 to be resource, integer given
in C:\xampp\htdocs\admin\mapcon.php on line 20

On your if statement you are not comparing the value:
if ($result = 0) { ....
You are setting 0 to $result.
You should use
if ($result == 0) { ...

Why does a Javascript function, issued from PHP not found?

I am perplexed. I have done this before and know this should work but cannot understand why the function is not found. Perhaps a second set of eyes will uncover the mystery.
I have tested its existence using JavaScript. See the console log below.

EDIT:
Please note the commented within the PHP code. That does not work either.

You are calling the function:
<script type='text/javascript'>stopUpload(1);</script>
But before you call it you need to load your JS:
<script src='./pathto/something.js'></script>; <!-- something.js declares stopUpload -->
<script type='text/javascript'>stopUpload(1);</script>

Variable getting via Ajax is empty ( Phonegap-Ajax-Json-PHP-MySQL )

I created an android application using Phonegap. I made an account in 000webhost and I've added my PHP files on the server. In the phpMyAdmin, I've created my database.
Right, now I tried to connect my project with the online database and insert or check some data in it.
PROBLEM:
When I run the application in my mobile phone i get this alert from the success: ... part of code in ajax :
There is no such username.
(my PHP had in comments all the echo, except the: echo json_encode)
When I added this line (var_dump($_POST);) right after i am getting the $usernamefrom ajax in the PHP and run my app, I saw this alert: array(1){ [\"username\"]=> string(2) \"hi"\" }
When I added these lines: if (empty($username)) { echo '...' } , after I run my app, I saw that in the alert inside the error: ... part of the ajax, it is printed the echo that is inside this if. So, the $username is empty for sure.
This is my JavaScript file: (I get correctly for sure all the values from html so Focus on the two Ajax parts of code)

This is my PHP file in which I check if the username already exists (Username = Primary Key):
<?php

header('Access-Control-Allow-Origin: *');
//require_once('../database_config.php');
$server = "my***.000webhost.com";
$database = "a1****37_guideme";
$username = "a1****37_guideme";
$password = "*****";
$con = mysql_connect($server, $username, $password);
// if($con) { //echo "Connected to database!"; }
// else { //echo "Could not connect!"; }
mysql_select_db($database, $con);
$topost = file_get_contents('php://input');
$thedata = json_decode($topost, true);
$username = $thedata['username'];
//var_dump($_POST);
//if (empty($username)) {
// echo 'The username is either 0, empty, or not set at all';
//}
$sql = "SELECT COUNT(*) as Count FROM `user` WHERE `username`='$username'";
$result= mysql_query($sql, $con);
$rows = mysql_fetch_array($result);
$count = $rows['Count'];
if (!$result) {
die('Error: ' . mysql_error());
//$response_array['status'] = 'error';
//echo json_encode($response_array);
}
else {
if ($count == 0) {
echo json_encode(array('status' => 'success','message'=> 'There is no such username'));
//$response_array['status'] = 'success';
//echo json_encode($response_array);
}
else
{
echo json_encode(array('status' => 'error','message'=> 'The username already exists'));
//$response_array['status'] = 'error';
//echo json_encode($response_array);
}
}
mysql_close($con);
?>
And this is the PHP file in which I tried to insert the new entry in my database ( my credentials are for sure correct):
<?php

//require_once('database_config.php');
