write method produce a huge memory leak!

workaround: use getResource



==============8<===========================



$chunkSize = intval($f->file['chunkSize']);

//echo $chunkSize;

$stream = $f->getResource();

$outStream = fopen($tmp,'wb');

while (!feof($stream)) {

   fwrite($outStream, fread($stream, $chunkSize));

}

fclose($stream);

fclose($outStream);

unset($stream);

unset($outStream);
