如何利用codeigniter建立一个简单的helloworld,本节介绍如何建立视图和控制器。首先在application/controllers文件夹下面建立一个hello.php

<?php
// application/controllers/hello.php
class Hello extends CI_Controller {
  public function index() {
    view_params = array (          'title' => '欢迎使用CodeIgniter',          'message' => 'Hello World!'       );      this->load->view ( 'helloview', $view_params );
  }
}

然后在application/views文件夹下面建立helloview.php

<!DOCTYPE html>
<html lang="zh">
<head>
<meta charset="utf-8">
<title><?php echo title ?>        

title?></h1> <hr> <p><?php echo $message?></p> </body> </html>

最后打开浏览器http://localhost/index.php/hello

ci_hello
