PHP cURL not working for localhost with remote server relation - php

Question

I'm currently working on copying a file from localhost to a remote server using PHP cURL.
I have two separate files, one for the localhost which sends the file, and another for the remote server to receive the file and save it to the server. The codes are as follows :
send.php
<?PHP
$web_page_to_send = "http://admin123.unaux.com/receive.php";
$file_name_with_full_path = "test.jpg";
$post_request = array
(
"sender" => "tmp",
"file" => curl_file_create($file_name_with_full_path)
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $web_page_to_send);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_request);
$result = curl_exec($ch);
curl_close($ch);
echo "<br>Result: ".$result;
?>
receive.php
<?PHP
if(isset($_POST['sender']))
{
echo "got it !";
$file_name = "tmp/".$_POST['sender']."-".$_FILES['file']['name'];
move_uploaded_file($_FILES['file']['tmp_name'], $file_name);
echo "Successful Attempt! <br><br>Filename: ".$file_name;
echo '<br><br> <img src="'.$file_name.'" width="300px"></img>';
}
else
{
echo 'Unauthorized Access!';
}
?>
The codes are working fine on localhost, but after placing the receive.php to the remote server, the file is no more sent and displayed. "http://admin123.unaux.com/receive.php" is where the file is on the remote server. I'm using profreehost free server as the remote server.

Can anyone please help me with this problem?
Thank you.

Please get all received data in the receive.php file as below:
$post_data = trim(file_get_contents("php://input"));
after this, try to print $post_data. If you will get null value then response is not hitting at your file.
Try to send above data with below code:
$web_page_to_send = "http://admin123.unaux.com/receive.php";
$file_name_with_full_path = "test.jpg"; // Please write here full file path in the system
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => $web_page_to_send,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 20,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => array('sender' => 'tmp','file'=>new CURLFILE($file_name_with_full_path)),
CURLOPT_HTTPHEADER => array(
"Content-Type: image/jpg"
),
CURLOPT_UPLOAD=>true,
));
$response = curl_exec($curl);
$http_response = curl_getinfo($curl, CURLINFO_HTTP_CODE);
curl_close($curl);
