CURL POST with file - 不在Windows上运行

I have a php script that sends a file via cURL, to a remote location.

This works great on a Mac.

On Windows w/ MAMP (I am stuck with this at present), no request reaches the remote server.

If I take away the CURLOPT_POSTFIELDS parameter, the request is sent, however without my data (obviously). This tells me that cURL is loaded ok, and is able to send a request.

What I can't work out, is what is causing this to do nothing when CURLOPT_POSTFIELDS is included (as per the code below) - no errors (that I am aware of).

Here is the code that I am running:

function getCurlValue($filename, $contentType, $postname)
{
    if (function_exists('curl_file_create')) {
        return curl_file_create($filename, $contentType, $postname);
    }

    // Use the old style if using an older version of PHP
    $value = "@{$this->filename};filename=" . $postname;
    if ($contentType) {
        $value .= ';type=' . $contentType;
    }

    return $value;
}

$filename = 'c:\path\to\file\test.txt';
$cfile = getCurlValue($filename,'text/plain','test.txt');

$data = array('updateFile' => $cfile);

$ch = curl_init();
$options = array(CURLOPT_URL => 'http://url/to/my/service',
             CURLOPT_RETURNTRANSFER => true,
             CURLINFO_HEADER_OUT => true, //Request header
             CURLOPT_HEADER => true, //Return header
             CURLOPT_FAILONERROR => true,
             CURLOPT_FOLLOWLOCATION => true,
             CURLOPT_SSL_VERIFYPEER => false,
             CURLOPT_POST => true,
             CURLOPT_POSTFIELDS => $data
            );

curl_setopt_array($ch, $options);
$result = curl_exec($ch);
$header_info = curl_getinfo($ch,CURLINFO_HEADER_OUT);
$header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE);
$header = substr($result, 0, $header_size);
$body = substr($result, $header_size);
curl_close($ch);

I have checked for cURL errors, of which there are none thrown.

Any thoughts would be most appreciated.

Thanks,

Nathan

This issue appears to have resolved itself. All is now working, with no changes on my part.

Must have been something at the server end....
