MVC:
class Nb_model extends CI_Model {
public function __construct()
{
//连接数据库
$this->load->database();
}
public function get(){
//查询数据库
$query=$this->db->get('users');
//以数组形式返回查询结果
return $query->result_array();
}
}
//防止非法访问
if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Nb extends CI_Controller {
public function __construct()
{
parent::__construct();
//加载数据模型
$this->load->model('nb_model');
}
public function index()
{
//根据数据模型获取数据
$data['nb']=$this->nb_model->get();
//加载视图文件
$this->load->view('nb',$data);
}
}
//文件末尾注释
