Getting json_encode(): type is unsupported, encoded as null

Question

I am working on web services where am using json_encode() to send my response . It is working fine for every ther web service but I am getting json_encode(): type is unsupported, encoded as null for the following code only.

public function getjobdetailsAction()
    {
        $this->_helper->layout ()->disableLayout ();
        $this->_helper->viewRenderer->setNoRender ( true );

        $handle = fopen ( 'php://input', 'r' );
        $jsonInput = fgets ( $handle );

        $params = Zend_Json::decode ( $jsonInput );


        if($params['user_id'] != "" && $params["job_id"] != "")
        {
            $job_id = $params["job_id"];
            $jobObj=Extended\job::getRowObject( $job_id );
            //check if job obj exist only then send job array to view.
            if($jobObj)
            {
                $job_detail_r = array();
                $job_detail_r['job_id'] = $job_id;
                $job_detail_r['job_created_by'] = $jobObj->getIlookUser()->getId();
                $job_detail_r['job_title'] = $jobObj->getJob_title();

                $job_detail_r['apply_from'] = $jobObj->getApply_from();
                if($jobObj->getJob_image() != "")
                {
                    $job_detail_r['company_image'] = IMAGE_PATH."/jobs/".$jobObj->getJob_image();
                }
                else 
                {
                    $job_detail_r['company_image'] = IMAGE_PATH.'/no_image.png';
                }
                $job_detail_r['is_saved'] = Extended\saved_jobs::isJobSavedByMe($job_id,$params['user_id']);

                $code = 200;
                $msg = "Job details retrieved successfully";
                $result = array("jobdetails"=>$job_detail_r);

            }
            else
            {
                $code = 301;

            }
        }
        else
        {
            $code = 301;
            $msg = "Missing parameters";
        }
        echo Helper_common::successFailureMsgs($code,$msg,$result);
        exit();






public static function successFailureMsgs( $code, $message, $result = array())
    {

        if($code == 200)
        {
             $result1 = array("Response"=>array("Code"=>$code,"Status"=>"OK","Message"=>$message,"result"=>$result));
        }
        else
        {
             $result1 = array("Response"=>array("Code"=>$code,"Status"=>"Error","Message"=>$message));
        }
        return Zend_Json::encode($result1);

    }

In response I am getting correct response but the above error as well . Please assist. Thanks in advance.

For json_encode(), and therefore Zend_Json(), all types are accepted except resource.

So you have debbuger your table to see where the resource is located. You can try something like this:

foreach ($job_detail_r as $k => $v){
    if (is_resource($v))
        echo $k . ' => ressource type = ' . get_resource_type($v);
}

Thank you doydoy44. I have used get_stream_contents to change resource into string and now its working fine.
