Merhaba arkadaşlar, curl ile veri çekerken json_encode ve $this->output->set_status_header('404'); engeline takılıyorum.
Aşağıda kullandığım curl fonksiyonun verdim.

function cek_gelsin($sayfam)
    {
    $ch = curl_init();
    //$ch = curl_init('http://example.com/service/get_video_part'); 
    $data = array("video_id" => "$sayfam", "part_name" => "480p", "page" => "0"); 
    // "video_id=$sayfam&part_name=480p&page=0"                                                    
    $data_string = json_encode($data);
    curl_setopt($ch, CURLOPT_URL, 'http://example.com/service/get_video_part');
    //cache:false
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
        'Accept: application/json, text/javascript, */*; q=0.01"',
        'Content-Type: application/json; charset=utf-8',                                                                                
        'Content-Length: ' . strlen($data_string))                                                                       
    );
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    //curl_setopt($ch, CURLOPT_REFERER, 'http://www.cloudflare-watch.org/cgi-bin/cfsearch.cgi');
    curl_setopt($ch, CURLOPT_REFERER, 'http://example.com/referer-adress.html');
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_VERBOSE, true);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.3; WOW64; rv:34.0) Gecko/20100101 Firefox/34.0');
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");     
    //curl_setopt($ch, CURLOPT_POSTFIELDS, "video_id=$sayfam&part_name=Alternatif+&page=0");
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
    $exec = trim(curl_exec($ch));
    curl_close($ch);
    return $exec;
    }
    $dene="64";
    echo cek_gelsin($dene);

Alttaki kod service/get_video_part php fonksiyonuna ait.

  function get_video_part(){
      if($this->input->is_ajax_request()){
          $this->form_validation->set_rules('video_id', 'video_id', 'required|numeric|xss_clean');
          $this->form_validation->set_rules('page', 'page', 'required|numeric|xss_clean');
          $this->form_validation->set_rules('part_name', 'part_name', 'required|xss_clean');
          if ($this->form_validation->run() == TRUE){
              $this->load->library('videos');
              if($data  = $this->videos->get_video_part($this->input->post('video_id'), $this->input->post('part_name'), $this->input->post('page'))){
                  $this->output->set_content_type('application/json')->set_output(json_encode($data));
                  return false;
              }
          }
          $this->output->set_status_header('404');
      }
      $this->output->set_status_header('404');
       echo '@nothing@';
  }

Bu header 404 engelini nasıl aşarım.
