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 /* End of file nb.php */ /* Location: ./application/controllers/nb.php */
<html> <head> <title>CI heiilo world</title> </head> <body> <!--循环输出数据--> <?php foreach($nb as $v):?> <h1><?=$v['email']?></h1> <?php endforeach?> </body> </html>
