Decoding JSON after sending using PHP cUrl

Hi,

I've researched everywhere and cannot figure this out.

I am writing a test cUrl request to test my REST service:

// initialize curl handler
$ch = curl_init();

$data = array(
"products" => array ("product1"=>"abc","product2"=>"pass"));
$data = json_encode($data);

$postArgs = 'order=new&data=' . $data;

// set curl options
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLINFO_HEADER_OUT, TRUE);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postArgs);
curl_setopt($ch, CURLOPT_URL, 'http://localhost/store/rest.php');

// execute curl
curl_exec($ch);

This works fine and the request is accepted by my service and $_Post is populated as required, with two variables, order and data. Data has the encoded JSON object. And when I print out $_Post['data'] it shows:

{"products":{"product1":"abc","product2":"pass"}}

Which is exactly what is expected and identical to what was sent in.

When I try to decode this, json_decode() returns nothing!

If I create a new string and manually type that string, json_decode() works fine!

I've tried:

strip_tags() to remove any tags that might have been added in the http post utf8_encode() to encode the string to the required utf 8 addslashes() to add slashes before the quotes

Nothing works.

Any ideas why json_decode() is not working after a string is received from an http post message?

Below is the relevant part of my processing of the request for reference:

public static function processRequest($requestArrays) {
    // get our verb
    $request_method = strtolower($requestArrays->server['REQUEST_METHOD']);
    $return_obj = new RestRequest();
    // we'll store our data here
    $data = array();

    switch ($request_method) {
        case 'post':
            $data = $requestArrays->post;
            break;
    }

    // store the method
    $return_obj->setMethod($request_method);

    // set the raw data, so we can access it if needed (there may be
    // other pieces to your requests)
    $return_obj->setRequestVars($data);

    if (isset($data['data'])) {
        // translate the JSON to an Object for use however you want
        //$decoded = json_decode(addslashes(utf8_encode($data['data'])));
        //print_r(addslashes($data['data']));
        //print_r($decoded);
        $return_obj->setData(json_decode($data['data']));
    }
    return $return_obj;
 }
