如何制作计数数据

Question

public function index()
{
    $yek = $this->input->post("KEY");
    $cek = $this->m_user->get('KEY' => $yek)->num_rows();//line 14
    $response = array();
    if ($cek > 1)
    {
        $list = $this->m_masalah->jenis();
    }
    foreach ($list as $key ) {
        $arr = array();
        $arr['ID_MASALAH']      = $key['ID_MASALAH'];
        $arr['MASALAH']         = $key['MASALAH'];
        $arr['JENIS']           = $key['JENIS'];
        array_push($response, $arr);
    }
    echo $json_response = json_encode($response);
} 

这是我的错误
