How to use stream_notification_callback with cURL

Question

Is it possible to use stream_notification_callback with cURL?
I would like to adapt example # 1, which I found here http://www.php.net/manual/en/function.stream-notification-callback.php , to my cURL function below, to create / update a text file that contains loaded bytes.

I know what is CURLOPT_PROGRESSFUNCTIONimplemented in php 5.3, but I am running php 5.2 and I can’t upgrade.

private function Save($url) {
    $this->SetTempFileName(time());
    $file = fopen($this->GetTempVidFileName(), 'w');
    $ckfile = tempnam("/tmp_cookie", "CURLCOOKIE");
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_FILE, $file);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_COOKIEFILE, $ckfile);
    curl_setopt($ch, CURLOPT_COOKIEJAR, $ckfile);
    curl_exec($ch);
    curl_close($ch);
    fclose($file);
    return is_file($this->GetTempFileName());
}

I know that I will have to use file_put_contents to replace the case STREAM_NOTIFY_PROGRESS part like this ...

case STREAM_NOTIFY_PROGRESS:
file_put_contents('progress.txt', $bytes_transferred);
break;

... but my question is how to adapt two codes? Thanks in advance.
