Jermoe suggested the following code:

If you want to get the header field content, use CURLOPT_HEADER as follows:

$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL,
"https://secure.authorize.net/gateway/transact.dll");
curl_setopt ($ch, CURLOPT_HEADER, 1);
ob_start();
curl_exec($ch);
$string = ob_get_contents();
ob_end_clean();
curl_close($ch);

You get in $string the header field content and the response from the
server. Then you just have to extract the information
that you need with strpos and substr, or preg_match_all.

Hope this helps.

===========================================================

It works for a non-SSL site. But with the site I listed above,
I get nothing back from the SSL site. From a browser, I do get back a body
saying invalid username,password but from within my php script, nothing
comes back. I noticed that the web server I am running from is using libcurl
7.8 with Redhat 7.2 and openssl 0.9.6b. So is the only problem that my web
server needs to be updated to libcurl 7.10.2? What is the minimum version of
libcurl needed to do https??
