how to decode posted parameters in php

Dear Experts,

I post a payment request to a payment website, then the web site returns me the below data as a succesful result.

I get the result like this

$raw = file_get_contents('php://input');
and when I print_r($raw); I get the below result.

I want to decode the result and put the parameters into arrays however I can not decode it properly.
How can I decode it?
I tried to decode it like below twice. When I did that, it only gives me the result but it doesn't give the header of the result.
what do you suggest I should do?
$new = urldecode($raw);
$new = urldecode($new);

I believe you want something like this:

parse_str($raw, $output);
$raw_xml = urldecode($output['DATA']);
$xml = simplexml_load_string($raw_xml);

print_r($xml);

Dear poohbear_68
thank you for your promt reply.

when I do that it gives me the result like this

DATA=282017-08-22 13:10:30ZHALDbRXQ1vNffcN7GKftmzfLyyTiEYFKezQyQPhHok2017-08-22 16:08:53Zwebmaster3920193651KL40642P00001936511802Nzor Depo100100,0000false20Özel Çımolyğlu**********32321940011402017-08-22 16:09:19Z1,001,00097476&HASH=3644f5538552869aa14a00eeaf380b751b7d6b8d971a15ab66fcfcb6a646dcc0

how can I separate them? it should give me like this : Reference => KL40642P0000193651 or Reference : KL40642P0000193651

HainKurt

we can use this function

$DATA="DATA=%253c%253fxml%2Bversio...";
$decDATA = urldecode (rawurldecode ($DATA));

result will be

I use PHP version: 7.1
when you use your function, do you get a different result? is it because of my php version?

I got some error related to utf 8 / 16 but fixed as below

//decode and decode
$decDATA = urldecode (rawurldecode ($DATA));
//remove hash part
$xmlDATA = substr($decDATA, 0, strpos ($decDATA, "&HASH"));
//change encoding
$xmlDATA = preg_replace('/(<\?xml[^?]+?)utf-16/i', '$1utf-8', $xmlDATA);     
//load into xml object
$xml = simplexml_load_string($xmlDATA);

then we can use variables like this...

print_r($xml);
