this is actually scarily related to the unanswered question i signed up to this
list for...

proper solution without downloading the file twice:
(but also using global variables)

<?
// these should really be stored inside the curl context
global $filename;
global $outfile;

function header_cb($handle,$h){
    global $filename;
    if(preg_match("/^Content-Disposition: .*filename\=([^\\n|\\r]+)[\\n\\r]/", $h, $m)){
        $filename=$m[1];
        echo "got filename: ".$filename."\n";
    }
    return strlen($h);
}

function data_cb($handle,$d){
    global $filename;
    global $outfile;
    if (!$outfile){
        $status=curl_getinfo($handle,CURLINFO_HTTP_CODE);
        if ($status != 200){
            echo "bad http status\n";
            return -1;
        }
        if ($filename == null){
            echo "there was no no filename in the headers...\n";
            return -1;
        }
        $outfile=fopen($filename,"w");
    }
    return fwrite($outfile,$d);
};

// testcase urls found via google:
$handle=curl_init("http://blog.ninedays.org/demo/direct-to-download-images-and-pdfs/download.image.php");
//$handle=curl_init("http://blog.ninedays.org/demo/direct-to-download-images-and-pdfs/original.jpg");

curl_setopt($handle,CURLOPT_WRITEFUNCTION,"data_cb");
curl_setopt($handle,CURLOPT_HEADERFUNCTION,"header_cb");
$filename=null;
if (!curl_exec($handle)){
    echo curl_error($handle)."\n";
}
if ($outfile) fclose($outfile);
curl_close($handle);

?>
