Codeigniter中控制器的回显/打印查询结果

Question

I am trying to display my Model query return result in my controller, but I don't know how to do it. could you please show me? Thanks in advance

Controller:

function updateJobsheetCDC()
    {
        $prnID = $this->input->post('prnID');

        $this->load->model('Ipss_model');
        $data['prnEmail'] = $this->Ipss_model->prnEmailList($prnID);

        echo $data['prnEmail']['name'];
    }

Model:

function prnEmailList($prnID)
    {
        $q = $this->db->query("SELECT pm.* , prm.*,e.* from  principal_master pm ,principal prm,email e where pm.prnID=e.prnID and prm.prID= pm.prID and e.prnID='" .$prnID."'");

        if($q->num_rows()>0) {
          foreach($q ->result() as $row) 
          {
             $data[] = $row;    
          }
          return $data;
        }       
    }

I have tried echo $data['prnEmail']['name']; but it do not work. It shows Severity: Notice

Message: Undefined index: name.

You have multi-dimentinal array returning from model. So you have to loop over them then print data

function updateJobsheetCDC()
{
    $prnID = $this->input->post('prnID');

    $this->load->model('Ipss_model');
    $data = $this->Ipss_model->prnEmailList($prnID);
    foreach ($data as $key => $value) {
      echo $value->name; 
    }
}
