Elastic search and Codeigniter (PHP)


I'm trying using ElasticSearch with Codeigniter framework.

What i did is just install ElasticSearch and copyed ( :P ) a good PHP library found on the web to CI libraries:

    class Elasticsearch {

  public $config_file = 'elasticsearch';
  public $index;

  function __construct($index = false){
      $CI =& get_instance();
      $CI->config->load($this->config_file);
      $this->server = $CI->config->item('es_server');

  }

  function call($path, $http = array()){
    if (!$this->index) throw new Exception('$this->index needs a value');
    return json_decode(file_get_contents($this->server . '/' . $this->index . '/' . $path, NULL, stream_context_create(array('http' => $http))));
  }

  //curl -X PUT http://localhost:9200/{INDEX}/
  function create(){
     $this->call(NULL, array('method' => 'PUT'));
  }

  //curl -X DELETE http://localhost:9200/{INDEX}/
  function drop(){
     $this->call(NULL, array('method' => 'DELETE'));
  }

  //curl -X GET http://localhost:9200/{INDEX}/_status
  function status(){
    return $this->call('_status');
  }

  //curl -X GET http://localhost:9200/{INDEX}/{TYPE}/_count -d {matchAll:{}}
  function count($type){
    return $this->call($type . '/_count', array('method' => 'GET', 'content' => '{ matchAll:{} }'));
  }

  //curl -X PUT http://localhost:9200/{INDEX}/{TYPE}/_mapping -d ...
  function map($type, $data){
    return $this->call($type . '/_mapping', array('method' => 'PUT', 'content' => $data));
  }

  //curl -X PUT http://localhost:9200/{INDEX}/{TYPE}/{ID} -d ...
  function add($type, $id, $data){
   echo  $this->call($type . '/' . $id, array('method' => 'PUT', 'content' => $data));
  }

  //curl -X GET http://localhost:9200/{INDEX}/{TYPE}/_search?q= ...
  function query($type, $q){
    return $this->call($type . '/_search?' . http_build_query(array('q' => $q)));
  }
}
then i'm trying creating indexes and simply retrieve them:

$this->load->library('elasticsearch');
                 $this->elasticsearch->index = 'comments';
                 $this->elasticsearch->create();
                 $data = '{author:jhon,datetime:2001-09-09 00:02:04}';
                 $this->elasticsearch->add($type ='details',$id = '1',$data);
when i run this code it show me errors:
