PHP curl file not downloading

[fheppell]

The output of this code is a 0 byte file:

if ($_GET['download']== 'true'){
          $downloadarray = array();
          while($row = mysql_fetch_array($res)){
            $url= $row['loc'];
            $path = 'tmp/';
            $path .= rand(100,999);
            $path .= $row['name'];
            $fp = fopen($path, 'w');
            $ch = curl_init($url);
            curl_setopt($ch, CURLOPT_FILE, $fp);     
            $data = curl_exec($ch);     
            curl_close($ch);
            fclose($fp);
            echo print_r($data);
            $downloadarray[] =  array($path, $row['name']);
          }
        //this stuff is not included in the OP
         $zipname = rand(0,9999) . 'download.zip';
          $zip = new ZipArchive;
          $zip->open($zipname, ZipArchive::CREATE);
          foreach ($downloadarray as $file) {
            $zip->addFile($file['0'], $file['1']);
          }
          $zip->close();
          header('Content-Type: application/zip');
          header('Content-disposition: attachment; filename=' . $zipname);
          header('Content-Length: ' . filesize($zipname));
          readfile($zipname);
          unlink($zipname);
        }

The zip is corrupt as well. Any ideas?

I have to say, I've had issues with ZipArchive too - haven't tried the putative solution yet though.

I should probably have made the OP clearer. The curled file (in the tmp/ directory) is 0 bytes and the zip is also corrupt.
