Returning a PHP value to a Coldfusion page? -

i'm doing cfhttp post php page:

<cfhttp method="post" url="https://www.example.com/ssl/roundpoint.php" result="mlresponse">   <cfhttpparam type="header" name="accept-encoding" value="deflate;q=0">  <cfhttpparam type="header" name="te" value="deflate;q=0"> <cfoutput>      <cfif isdefined( "ppcid" )><cfhttpparam name="ppcid" type="formfield" value="#ppcid#"></cfif>     <cfif isdefined( "product")><cfhttpparam name="product" type="formfield" value="#product#"></cfif>     <cfif isdefined( "va_status" )><cfhttpparam name="va_status" type="formfield" value="#va_status#"></cfif>     <cfif isdefined( "qs_product")><cfhttpparam name="qs_product" type="formfield" value="#qs_product#"></cfif>     <cfif isdefined( "prop_st" ) , prop_st neq ""><cfhttpparam name="prop_st" type="formfield" value="#prop_st#"></cfif>  </cfoutput> </cfhttp> 

on php page, curl function, specific value in result , save it:

 $pstvars = '';   if (count($_request) > 0) {     foreach($_request $key=>$value) {        $pstvars .= $key . '=' . urlencode($value) . '&';      }      $pstvars .= 'on_submit=yes';       //the ssl/organic redirect api url      $url = 'https://www.example.com/ssl/redirect.php';       //make server-side redirect api call     $ch = curl_init();     curl_setopt($ch, curlopt_url, $url);     curl_setopt($ch, curlopt_post, true);     curl_setopt($ch, curlopt_postfields, $pstvars);     curl_setopt($ch, curlopt_ssl_verifypeer, false);     curl_setopt($ch, curlopt_returntransfer, 1);      //store result api call     $roundpoint_result = curl_exec($ch);      // looking roundpoint flag     $rpvals = substr($roundpoint_result, 0, 10); 

for testing purposes, i've e-mailed myself $rpvals value make sure it's correct. need pass value coldfusion page. i've tried passing value cookie:

 setcookie('rpcookie', $rpvals, time()+60*60*24*2, '/', '.example.com'); 

and tried read on coldfusion page:

<cfparam name="rpcookie" default=""/> <cfcookie name="rpcookie" value="#rpcookie#"> 

but haven't had luck this, either setting cookie or reading in coldfusion. suggestions?

(fyi - coldfusion page re-written in php in few weeks, client requesting time sensitive).
