PHP - create XML file?

Hi,
I am trying to create an XML file and then post to interparcel but not doing anything, not sure what I am doing wrong?

Your feedback would be appreciated.

<?php
// Your post data
//$post_city= $_POST['city'];
//$post_postcode = $_POST['postcode'];

$post_city= 'Melbourne';
$post_postcode = '3001';



// Building your XML string
$strXML = '<?xml version="1.0" encoding="UTF-8"?>'."\n";
$strXML .= '<Request>'."\n";
$strXML .= '<Authentication>'."\n";
$strXML .= '<UserID>admin@onlinestore.com.au</UserID>'."\n";
$strXML .= '<Password>onlinepass</Password>'."\n";
$strXML .= '<Version>1.0</Version>'."\n";
$strXML .= '</Authentication>'."\n";

$strXML .= '<RequestType>Rates</RequestType>'."\n";
$strXML .= '<ShowAvailability>N</ShowAvailability>'."\n";

$strXML .= '<Shipment>'."\n";

$strXML .= '<Collection>'."\n";

$strXML .= '<City>Niddrie</City>'."\n";
$strXML .= '<Country>Australia</Country>'."\n";
$strXML .= '<Postcode>3042</Postcode>'."\n";
$strXML .= '</Collection>'."\n";

$strXML .= '<Delivery>'."\n";
$strXML .= '<City>'.$post_city.'</City>'."\n";
$strXML .= '<Country>Australia</Country>'."\n";
$strXML .= '<Postcode>'.$post_postcode.'</Postcode>'."\n";
$strXML .= '</Delivery>'."\n";

$strXML .= '<Package>'."\n";
$strXML .= '<Weight>4</Weight>'."\n";
$strXML .= '<Length>43</Length>'."\n";
$strXML .= '<Width>46</Width>'."\n";
$strXML .= '<Height>66</Height>'."\n";
$strXML .= '</Package>'."\n";

$strXML .= '</Shipment>'."\n"; 
$strXML .= '</Request>'."\n";


$url = "https://www.interparcel.com.au/api/xml/rates.php";

$post_string = $strXML;


$header = "POST HTTP/1.0 \r\n";
$header .= "Content-type: text/xml \r\n";
$header .= "Content-length: ".strlen($post_string)." \r\n";
$header .= "Content-transfer-encoding: text \r\n";
$header .= "Connection: close \r\n\r\n"; 
$header .= $post_string;

$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); 
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 4);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $header);

$data = curl_exec($ch); 

if(curl_errno($ch))
print curl_error($ch);
else
curl_close($ch);

You might find this easier with HEREDOC notation.  Also, I believe that you must tell cURL that you're using a POST-method request.  This is my teaching example. YMMV, but it appears to work most of the time and it can give you error diagnostic information if it fails.

function curl_post($url, $post_array=array(), $timeout=2, $error_report=TRUE)
{
    // PREPARE THE POST STRING
    $post_string = NULL;
    foreach ($post_array as $key => $val)
    {
        $post_string .= $key . '=' . urlencode($val) . '&';
    }
    $post_string = rtrim($post_string, '&');

    // PREPARE THE CURL CALL
    $curl = curl_init();
    curl_setopt( $curl, CURLOPT_URL,            $url           );
    curl_setopt( $curl, CURLOPT_HEADER,         FALSE          );
    curl_setopt( $curl, CURLOPT_POST,           TRUE           );
    curl_setopt( $curl, CURLOPT_POSTFIELDS,     $post_string   );
    curl_setopt( $curl, CURLOPT_ENCODING,       'gzip,deflate' );
    curl_setopt( $curl, CURLOPT_TIMEOUT,        $timeout       );
    curl_setopt( $curl, CURLOPT_RETURNTRANSFER, TRUE           );
    curl_setopt( $curl, CURLOPT_FOLLOWLOCATION, TRUE           );

    // EXECUTE THE CURL CALL
    $htm = curl_exec($curl);
    $err = curl_errno($curl);
    $inf = curl_getinfo($curl);

    // ON FAILURE
    if (!$htm)
    {
        // PROCESS ERRORS HERE
        if ($error_report)
        {
            echo "CURL FAIL: $url TIMEOUT=$timeout, CURL_ERRNO=$err";
            echo "<pre>\n";
            var_dump($inf);
            echo "</pre>\n";
        }
        curl_close($curl);
        return FALSE;
    }

    // ON SUCCESS
    curl_close($curl);
    return $htm;
}

Also, it looks like Postcode != PostCode (case-sensitive tags).

Give this a try.  It will at least get you a meaningful response!
