curl credit card processing tutorial?

Anon

Can anyone point me to a tutorial on using command line curl to process credit cards through a middleman like ibill? I'm building my first ecommerce site in PHP and I'm working on a billing mechanism, but PHP can't natively make https requests, which is what I need to do. Any information on specific URLs where I might find this would be greatly appreciated. I've already checked out devshed and phpbuilder, but haven't found anything substantial. Using the built-in "cybercash" support is not an option...the solution has to be independent of the billing vendor. Thank you.

I have done it with authorize.net CURL OpenSSL and PHP here is a sample of the code I used and the rest is up to you as far as getting CURL and OpenSSL running on your server
$curl = "/usr/local/bin/curl";
$my_authnet_userid = "";
$total = "1.00";
$cc_number = "41111111111111";
$cc_exp = "1002";
$invoiceno = "4365356536";
$billing_address = "";
$billing_address = urlencode($billing_address);
$billing_zip = "";
exec("$curl -d 'x_Login=$my_authnet_userid&x_Amount=$total&x_Card_Num=$cc_number&x_Exp_Date=$cc_exp&x_ADC_URL=FALSE&x_ADC_Delim_Data=TRUE&x_Invoice_Num=$invoiceno&x_Version=3.0&x_Address=$billing_address&x_Zip=$billing_zip' https://secure.authorize.net/gateway/transact.dll", $authorize, $ret);

$auth_return = split("\,", $authorize[0]);

// for debugging you can print the variables returned:
for ($idx = 0; $idx < 39; ++$idx) {
$pos = $idx+1;

echo "Code".$pos.": ".$auth_return[$idx]." ";
}

if($auth_return[0] == 1){

// this section passes these three variables to your processing form
// for order tracking purposes

  $auth_code = $auth_return[4];
  $avs_code = $auth_return[5];
  $trans_id = $auth_return[6];

} elseif($auth_return[0] == 2){

  echo "<b>Your order cannot be processed at this time, as your

credit card was not accepted. ";

} elseif($auth_return[0] == 3){

  echo "<b>An error has occurred and your order cannot be proces

sed at this time. ";

}

Thanks Louie, this helps– I wasn't sure how to chop up the return values. This should simplify things...
