First of all, when you are using PHP on a website, everything regarding PHP is
executed on the web server, so the users web browser will not do anything more
than send a form to your script.

If you want to have header information which curl sent to the server, you can
do the following before you use curl_close():

$sentheader = curl_getinfo($ch, CURLINFO_HEADER_OUT);

If you want to have the header you got from the remote server, then do the
following before curl_exec():

curl_setopt($ch, CURLINFO_HEADER_OUT, 1);

and before curl_close():

$header_size = curl_getinfo($ch, CURLINFO_HEADER_SIZE);
$header = substr($response, 0, $header_size);

If you are interested of seeing the header that the user sent when they posted
the the form:

$headers = apache_request_headers();

foreach ($headers as $header => $value) {
echo "$header: $value <br />\n";
}

This will only work on a apache server, depending on how you have setup the
apache server to execute php. There is suggestion on a work around which you
can read at:
