pdf form sends FDF instead of PDF

Question

UPDATE i discovered it sends PDF if opened by adobe reader at my computer, but same pdf form sends FDF if opened in Chrome browser at website UPDATE END

i am using Acrobat XI Pro trial version

Adobe Acrobat offer forms in pdf documents, those forms can be submitted to server

submit button settings http://gyazo.com/0ff0dc17210f39f062a131c85265406c

my server code

<?php

ob_start();
$file = file_get_contents("php://input"); //Gets binary PDF Data
$time = microtime(true);
$newfile = "./customers/" . $time . ".pdf"; //Names file based on the time to the microsecond so nothing gets overwritten.
$worked = file_put_contents($newfile, $file); //Creates File
ob_end_clean();

?>

and i am getting FDF data instead, not PDF document

FDF is one of the format pdf forms can export(includes form name and values only). data i am getting:

Chrome's PDF viewer is of limited quality only. I'm actually surprised it supports PDF form posting at all. — mkl, Mar 28 '15 at 19:53

In general Adobe PDF Forms full functionality available only in Adobe Reader. Google Chrome pdf viewer sends only FDF format. Firefox pdf viewer don't allow form editing/sending at all. Maybe obvious, but i am php developer and never worked with PDF Forms.
