I am working on integrating a credit payment service from setcom. on completion of transaction setcom sends bunch of post variables that my script has to send back to setcom to get the details of the transaction as an xml file.

I am using the pecl_http extension(http_post_fields) for posting these variables but i have this reponse header info with the xml file that i can't get rid of. And the php doc isnt explicit enough on the use of this function:

HTTP/1.1 200 OK Connection: close Date: Tue, 19 May 2009 21:56:02 GMT Content-Type: text/html; charset=UTF-8 Server: Microsoft-IIS/6.0 P3P: CP="IDC DSP CURa ADMa DEVa IVAa IVDa OUR DELa NOR LEG UNI PUR NAV INT DEM" X-Powered-By: ASP.NET Set-Cookie: CFID=142013;expires=Thu, 12-May-2039 21:56:02 GMT;path=/ Set-Cookie: CFTOKEN=99801499;expires=Thu, 12-May-2039 21:56:02 GMT;path=/ <?xml version='1.0' encoding='UTF-8'?><order_synchro><outcome><status>Complete</status>
i need to work with the xml file but the response header with the xml file is really not allowing me to.

How can i set the http_post_field function not to return response headers?

Help needed thanks in advance!
