How to process data stream in PHP?

Question

PHP

I am developing an application for Windows Phone on WinJS and it became necessary to upload a file (image or video) to the PHP server, since the application is a site client.
The only API for uploading files to the server in Windows Phone passes the file name through the headers header, you can get it like this:

$headersCont = apache_request_headers();
$headersCont[Filename] - имя файла

And the file itself is transmitted through the data stream. How can I get this image and transfer it to the right folder on the PHP server?
This is how it displays only the text Resource #6

$hSource = fopen('php://input', 'r');
echo $hSource;

Maybe I'm misunderstanding something, here is a link to an article with the API:

Thank you for your help.

Answer 1

fopen opens the handle for reading/writing and declares the resource
__DIR__ the current folder where the script is

// читаем
$rawData = file_get_contents("php://input");
// пишем
$pathUploadDir = __DIR__ . "/uploadDir"
file_put_contents($pathUploadDir . '/' . $fileName ,  $rawData );

Answer 2

Line Reading Example

$lines = array();
$fileHandler = fopen("php://stdin", "r"); 	
while( !feof($fileHandler) AND ($line! = '') ) { 
  $lines[] = fgets($fileHandler,255); 
} 
fclose($fileHandler);

print_r($lines);

For images, perhaps it is better not line by line, but in blocks
