Question

I am new to PHP, and I am using it to POST data from an iPhone. I have written a basic code to get data from the iPhone, post it to the php script on my server, and then using PHP, send that data to another webserver. However, the webserver is returning a response in XML, and since I am a newbie to PHP, I need help with it.
My code to send data:

<?php
$ch = curl_init("http://api.online-convert.com/queue-insert");
$count = $_POST['count'];

$request["queue"] = file_get_contents($count);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $request);
$response = curl_exec($ch);
curl_close ($ch);
echo $response;
?>

I know I need to parse the XML response, but I have no idea how to do that. The XML response would be something like this:

    <?xml version="1.0" encoding="utf-8"?>
<queue-answer>
  <status>
    <code>0</code>
    <message>Successfully inserted job into queue.</message>
  </status>
  <params>

  </params>
</queue-answer>

You’re probably looking for SimpleXML or DOMDocument.

SimpleXML

To load data from a string into an object: simplexml_load_string().

DOMDocument

To create one from a string: DOMDocument->loadXML().
