When we install CodeIgniter 4, we should see a default landing page which will be something like this.
How can we find it’s files from where it is coming.
Default Controller
Go inside /app/Controllers folder, you will see we have a default called Home.php.
Open that controller, it will be like this.
<?php
namespace App\Controllers;
class Home extends BaseController
{
public function index()
{
return view('welcome_message');
}
}So, this is application default controller after installation. Inside this index() method we can see we have a view file attached welcome_message.
Default View File
Go inside /app/Views folder. We will see a default view file welcome_message.php. Inside that file we will have all the code which is responsible to render the output of landing page.
Default Route
Open Routes.php file from /app/Config folder. We will see we have default route in it as –
$routes->get('/', 'Home::index');
This route means – For landing page it has to run index() method from Home Controller. And inside index() method application returns welcome_message.php view file.
