php - How to get the array of a 2d array in codeigniter -

i have model,

function getdata($id) {     $arr=array(array());     $sql = "select id, title topic ....";     $query = $this->db->query($sql,array($id));     $arr[0][0] = $query->result();     $sql = "select id, title topic ....";     $query = $this->db->query($sql,array($id));     $arr[0][1] = $query->result();     return $arr; } 

and in controller, have code,

$data['check'] = $this->model->getdata("21313"); ... $this->load->view('check',$data); 

how can echo data?

i tried,

foreach($check[0][0] $row) {     echo $row->id;     echo $row->title; } 

but not working.

try print_r($data); first on controller

and check structure if $check model result can on view

foreach($check $row) {     echo $row->id;     echo $row->title; }
