如何將Controller中的數據傳遞給CodeIgniter中的View？

Question

如何將數據從控制器傳遞到CodeIgniter中的視圖？

控制器

<?php 
defined('BASEPATH') OR exit('No direct script access allowed'); 
class Hello extends CI_Controller {  
    public function index() 
    { 
     $data['hello']= "helloooo"; 
     $this->load->view('hello_world'); 
    } 
} 

Answer 1

<?php 
defined('BASEPATH') OR exit('No direct script access allowed'); 
class Hello extends CI_Controller {  
    public function index() 
    { 
     $data['hello']= "helloooo"; 
     $this->load->view('hello_world',$data); 
    } 
} 

在你看來

echo $hello; 

，並在視圖頁面程序hello_world參觀https://www.codeigniter.com/user_guide/

Answer 2

<?php 
defined('BASEPATH') OR exit('No direct script access allowed'); 

class Hello extends CI_Controller { 

    public function index() 
    { 
     $data['hello']= "helloooo"; 
     $this->load->view('hello_world',$data); 
    } 
} 

<?php 
echo $hello; 
?> 

Answer 3

加載視圖時將數據作爲參數傳遞。

$data['hello']= "helloooo"; 
$this->load->view('hello_world', $data);
