Parse an XML sent by PHP to another PHP script by curl

Thank you all, I have solved this and wrote my own answer on this question down below. Thank you all for trying

I have a simple (I hope) question as I am a complete newbie.

So I have 2 php files output.php and input.php.

output.php is sending an XML to input.php via cURL like so:

$myXML  = '<?xml version="1.0" encoding="UTF-8"?>'."\n";
$myXML .= '<request>
               <message>Hello StackOverflow</message>
               <params>
                   <name>John</name>
                   <lname>Smith</lname>
               </params>
           </request>';

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, 'http://localhost/curltest/input.php');
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $myXML);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER,
    array(
        'Content-type: text/xml; charset=UTF-8',
        'Expect: '
    )
);

$curl_response= curl_exec($curl);

Currently the contents of input.php look like this

<?php
// Yes, this is all

The problem is I don't know at all how to get and parse the XML data in input.php and take data out of that XML for use in my input.php script.

$_POST is an empty array in input.php, but the XML surely reaches input.php because readfile('php://input'); inside of input.php gives out the received XML.

I have read about DOMElement but it was kind of unclear to me how to use it in my specific case. I also did a search on Google and in SO also, but didn't succeed in finding exactly what I need.

If someone could tell me how exactly is this done it would be great. Or at least point me in the right direction, I'm at a loss here.

P.S. I can't change anything in output.php. And I will gladly provide any additional information if needed.

I've managed to solve it by getting the sent XML string into a variable in the input.php like so:

$xml_data = new SimpleXMLElement(file_get_contents('php://input'));
var_dump($xml_data);

Now I may do whatever I want with it. Thank you all for trying, you're all amazing!

you need to change

curl_setopt($ch, CURLOPT_POSTFIELDS, $myXML);

to 

curl_setopt($ch, CURLOPT_POSTFIELDS,  http_build_query(array('xml' => $myXML)));

then in your input.php file you can get the data using $_POST['xml'];

so in your input.php then do 

$xmldata = new SimpleXMLElement($_POST['xml']);

Simple XML is a really good library for XML parsing/reading/writing.

http://www.php.net/manual/en/book.simplexml.php

PHP:

$file = new SimpleXMLElement($file);
echo "<b>Testing:</b> {$file->testing} <br/>";

XML:

<document>
    <testing>Value</testing>
</document>

You can use Simple XML both from files and variables.

You can find more information about it here: http://www.php.net/manual/en/simplexmlelement.construct.php
