I am hoping someone can spot what is missing here.  I am getting null result

I try this url in my Firefox browser -

from Firebug below.)

In Firebug, this shows:

POST http://www.targetsite.com/ajax/search.xml

In Firebug, below this link are tabs for: Headers, Post, Response, XML and
Cookies.  Post tab shows like:

VAR1           1
VAR2           "2012-09-12"
VAR3           null
CACHED         []
OPTIONS        null

To prove there is output, the Firebug Response tab shows:

<?xml version="1.0" encoding="utf-8"?>
<JSON> various JSON encoded stuff </JSON>

The above is what I am trying to curl.

My php code:

   $ch = curl_init();
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
   curl_setopt($ch, CURLOPT_POST, 1);

   //target page from Firebug above:
   curl_setopt($ch, CURLOPT_URL,

   //I was not sure how to represent CACHED [], so set it to null
try "CACHED"=>array()
   $data = array(
     "VAR1" => 1,
     "VAR2" => "2012-09-12",
     "VAR3" => null,
   curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

   //make the request
   $result = curl_exec($ch);

   //this returns null

Any ideas where to go with this?  Maybe I need to include the Cookies? I use
the above php and curl functions normally so it's all installed on the


It might be that the site is using sessions/cookies. Have a look at
the header data with firebug.
Not sure if that's the problem, to find out what's really going on, call
echo curl_error($ch);
after curl_exec to find out what went wrong exactly.
If you still don't know how to proceed, paste the result of the
curl_error call in your reply.

I added the cookies to the post array. I changed php array to "CACHED"=>array() for the JSON "CACHED":[], and corrected php's null to NULL. It is not returning any error. The browser was showing 'resource not present' before I added the cookies to the post array, now it just returns null $result. Looks like I am transcribing something incorrectly.
