if you need the zip file from the response I guess you could just write a tmp file to save the curl response to, and stream that as a workaround:Never tried that with multipart curls, but I guess it should work.

$fh = fopen('/tmp/foo', 'w'); $cUrl = curl_init('http://example.com/foo'); curl_setopt($cUrl, CURLOPT_FILE, $fh); // redirect output to filehandlecurl_exec($cUrl); curl_close($cUrl);fclose($fh); // close filehandle or the file will be corrupted

if you do NOT need anything but the xml part of the response you might want to disable headers

curl_setopt($cUrl, CURLOPT_HEADER, FALSE);

and add option to only accept xml as a response

curl_setopt($cUrl, CURLOPT_HTTPHEADER, array('Accept: application/xml'));//That's a workaround since there is no available curl option to do so but http allows that

[EDIT]

A Shot in the dark...can you test with these curlopt settings to see if modifiying these help anything

$headers = array (    'Content-Type: multipart/form-data; boundary=' . $boundary,    'Content-Length: ' . strlen($requestBody),    'X-EBAY-API-COMPATIBILITY-LEVEL: ' . $compatLevel,  // API version    'X-EBAY-API-DEV-NAME: ' . $devID,    'X-EBAY-API-APP-NAME: ' . $appID,    'X-EBAY-API-CERT-NAME: ' . $certID,    'X-EBAY-API-CALL-NAME: ' . $verb,    'X-EBAY-API-SITEID: ' . $siteID,     );$cUrl = curl_init();curl_setopt($cUrl, CURLOPT_URL, $serverUrl);curl_setopt($cUrl, CURLOPT_TIMEOUT, 30 );curl_setopt($cUrl, CURLOPT_SSL_VERIFYPEER, 0);curl_setopt($cUrl, CURLOPT_SSL_VERIFYHOST, 0);curl_setopt($cUrl, CURLOPT_HTTPHEADER, $headers);curl_setopt($cUrl, CURLOPT_POST, 1);curl_setopt($cUrl, CURLOPT_POSTFIELDS, $requestBody);curl_setopt($cUrl, CURLOPT_RETURNTRANSFER, 1);curl_setopt($cUrl, CURLOPT_FAILONERROR, 0 );curl_setopt($cUrl, CURLOPT_FOLLOWLOCATION, 1 );curl_setopt($cUrl, CURLOPT_HEADER, 0 );curl_setopt($cUrl, CURLOPT_USERAGENT, 'ebatns;xmlstyle;1.0' );curl_setopt($cUrl, CURLOPT_HTTP_VERSION, 1 );      // HTTP version must be 1.0$response = curl_exec($cUrl);if ( !$response ) {    print "curl error " . curl_errno($cUrl ) . PHP_EOL;}curl_close($cUrl);

[EDIT II]

This is just a try, as mentioned I cannot get my curled pages to respond with a multipart form data. So be gentle with me here ;)

$content_type = ""; //use last know content-type as a trigger$tmp_cnt_file = "tmp/tmpfile";$xml_response = ""; // this will hold the "usable" curl response$hidx = 0; //header index.. counting the number of different headers receivedfunction read_header($cUrl, $string)// this will be called once for every line of each header received{     global $content_type, $hidx;    $length = strlen($string);    if (preg_match('/Content-Type:(.*)/', $string, $match))    {        $content_type = $match[1];        $hidx++;    }    /*     should set  $content_type to 'application/xop+xml; charset=utf-8; type="text/xml"' for the first     and to 'application/zip' for the second response body       echo "Header: $string<br />\n";    */    return $length;}function read_body($cUrl, $string){    global $content_header, $xml_response, $tmp_cnt_file, $hidx;    $length = strlen($string);    if(stripos ( $content_type , "xml") !== false)        $xml_response .= $string;    elseif(stripos ($content_type, "zip") !== false)    {        $handle = fopen($tmp_cnt_file."-".$hidx.".zip", "a");        fwrite($handle, $string);        fclose($handle);    }    /*    elseif {...} else{...}    depending on your needs    echo "Received $length bytes<br />\n";    */    return $length;}

and of course set the proper curlopts

// Set callback function for headercurl_setopt($cUrl, CURLOPT_HEADERFUNCTION, 'read_header');// Set callback function for bodycurl_setopt($cUrl, CURLOPT_WRITEFUNCTION, 'read_body');

don't forget to NOT save the curl response to a variable because of the memory issues,hopefully all you need will be in the $xml_response above anyways.

//$response = curl_exec($cUrl);curl_exec($cUrl);

And for parsing your code you can refer to $xml_response and the temp files you created starting with tmp/tmpfile-2 in this scenario. Again, I have not been able to test the code above in any way. So this might not work (but it should imho ;))

[EDIT III]

Say we want curl to write all incoming data directly to another (outgoing) stream, in this case a socket connection

I'm not sure if it is as easy as this:

$fs = fsockopen($host, $port, $errno, $errstr);$cUrl = curl_init('http://example.com/foo'); curl_setopt($cUrl, CURLOPT_FILE, $fs); // redirect output to sockethandlecurl_exec($cUrl); curl_close($cUrl);fclose($fs); // close handle

else we will have to use our known write and header functions with just a little trick

//first open the socket (before initiating curl)$fs = fsockopen($host, $port, $errno, $errstr);// now for the new callback functionfunction socket_pipe($cUrl, $string){     global $fs;    $length = strlen($string);    fputs($fs, $string); // add NOTHING to the received line just send it to $fs; that was easy wasn't it?    return $length;}// and of course for the CURLOPT part// Set callback function for headercurl_setopt($cUrl, CURLOPT_HEADERFUNCTION, 'socket_pipe');// Set the same callback function for bodycurl_setopt($cUrl, CURLOPT_WRITEFUNCTION, 'socket_pipe');// do not forget to fclose($fs); //when we're done

The thing is, not editing the result and simply piping it to $fs will make it necessary that apache is listening on a certain port which you then assign your script to.Or you will need to add ONE header line directly after fsockopen

fputs($fp, "POST $path HTTP/1.0\n"); //where path is your script of course

I'm sorry i can't help much because you did not put much code but i remember i was having a similar issue when i was playing with curl_setopt options.

Did you use CURLOPT_BINARYTRANSFER?

From php documentation -> CURLOPT_BINARYTRANSFER-> TRUE to return the raw output when CURLOPT_RETURNTRANSFER is used.

just set CURLOPT_RETURNTRANSFER CURLOPT_POST

        $c = curl_init($url);        curl_setopt($c, CURLOPT_RETURNTRANSFER, true);        curl_setopt($c, CURLOPT_CONNECTTIMEOUT, 1);        curl_setopt($c, CURLOPT_TIMEOUT, 1);        curl_setopt($c, CURLOPT_POST, 1);        curl_setopt($c, CURLOPT_POSTFIELDS,                    array());        $rst_str = curl_exec($c);        curl_close($c);
