PHP: http raw POST data contain BINARY

i have a device that send POST data to my server. so print_r($_POST) is empty, i can see the data only when i run this

$content = file_get_contents('php://input');
var_dump($content);   

//or i can use:  print_r($content);

i save those to a file and result are some json and BINARY DATA (CHECK IMAGE)SCREENSHOT

if i add code like this json_decode($content,true); i dont see anything

so how can i decode binary or what can i do to decode the json and also see what data is send in binary?

If you want to decode binary data inPHP, try the following:

<?php
$binarydata = "\x04\x00\xa0\x00";
$data = unpack('C*', $binarydata);
var_dump($data);

output:

array (size=4)
  1 => int 4
  2 => int 0
  3 => int 160
  4 => int 0

Load your contents from file_get_contents('php://input') to $binarydata and you will get an array of values. You can then apply some logic to extract JSON string and process it.
