In CodeIgniter, many settings have been configured, And we can modify them directly.

For example, to modify the default access page, there is a route. php In applications/config:

$route['default_controller'] = "welcome";$route['404_override'] = '';

Change default_controller to blog, and enter index. php In the taskbar. The output is HelloWorld, that is, the blog. php page is accessed:

Ii. Create and set a View

1. Create a file blog_view.php in the views directory:

2. Return to blog. php In the controller folder and load the blog_view page with simple echo to realize the true value of its controller:

 load->view('blog_view');}}?>

3. Enter the URL on the page to access the website. The page has changed:

3. data transmission between Controller and View

1. modify the code in Controller as follows:

2. Modify the display array in View as follows:

<?php echo $myName.$head?>I am

If you are not used to endforeach, you can also use the standard PHP language:

<?php echo $myName.$head?>I am 
 
 
 

  
  
  
 
  
 
 

Of course, you can also rewrite the constructor method:

 load->view('blog_view',$data);}}?>
