quickbooks online interaction - integration

Question

I have a web app that I need to communicate with quickbooks online edition. I am able connect and receive data. The problem is is that the responce back that i get is not in a xml format or even better would be in json formate. How can I get it to respond back in one of those formats? Here is my code:
function request($xml, $certificate = null, $debug = false){
$ch = curl_init();
$header[] = 'Content-Type: application/x-qbxml';
$header[] = 'Content-Length: ' . strlen($xml);
$params = array();
$params[CURLOPT_HTTPHEADER] = $header;
$params[CURLOPT_POST] = true;
$params[CURLOPT_RETURNTRANSFER] = true;
$params[CURLOPT_URL] = $this->gateway;
$params[CURLOPT_TIMEOUT] = 30;
$params[CURLOPT_POSTFIELDS] = $xml;
$params[CURLOPT_VERBOSE] = $debug;
$params[CURLOPT_HEADER] = true;
// This is only for the HOSTED security model
if (file_exists($certificate))
{
$params[CURLOPT_SSL_VERIFYPEER] = false;
$params[CURLOPT_SSLCERT] = $certificate;
}
// Some Windows servers will fail with SSL errors unless we turn this off
$params[CURLOPT_SSL_VERIFYPEER] = false;
$params[CURLOPT_SSL_VERIFYHOST] = 0;
// Diagnostic information: https://merchantaccount.quickbooks.com/j/diag/http
// curl_setopt($ch, CURLOPT_INTERFACE, '<myipaddress>');
$ch = curl_init();
curl_setopt_array($ch, $params);
$response = curl_exec($ch);
if (curl_errno($ch))
{
$errnum = curl_errno($ch);
$errmsg = curl_error($ch);
_log('CURL error: ' . $errnum . ': ' . $errmsg, $debug);
return false;
}
// Close the connection
#curl_close($ch);
// Remove the HTTP headers from the response
$pos = strpos($response, "\r\n\r\n");
$response = ltrim(substr($response, $pos));
return $response;
}
function item_list(){
$xml =
'<?xml version="1.0"?>
<?qbxml version="6.0"?>
<QBXML>
<SignonMsgsRq>
<SignonTicketRq>
<ClientDateTime>' . date('Y-m-d') . 'T' . date('H:i:s') . '</ClientDateTime>
<SessionTicket>' . $this->session . '</SessionTicket>

</SignonMsgsRq>

$response = $this->request($xml, null, true);
echo $response;
}

Answer 1

My stupid mistake. I was echoing my result to browser which interpreted xml tags as html tags. I used $xml = simplexml_load_string($response); print_r($xml); to view response in browser.
