Wrong POSTFIELDS Posted

I have a script that accepts four POST variables. Three are used and five more are added for a total of eight keys and their urlencode() values all strung together in the proper format. Then cURL is initialized with the field string given to: curl_setopt($ch, CURLOPT_POST,8); curl_setopt($ch, CURLOPT_POSTFIELDS, $string); But that's not the string arriving at cURL's target URL! What's arriving at the target is exactly the POST array that this script received in the first place. Here's what I don't understand... The cURL request is coming from this script on domainA, but the target address is also domainA. Does everybody play nice in this situation? PHP 5.3.5 Apache 2.2 Note: CURLOPT_POST evaluates to true, regardless that I use an integer. All other curl* commands are set.
