How to pass data from controller to view in CodeIgniter 4?

To pass data from a controller to a view in CodeIgniter 4, follow these steps:

1. Create a new controller or open an existing one.
2. Create an array of data that you want to pass to the view, for example:

$data = [
    'title' => 'Welcome to CodeIgniter 4!',
    'message' => 'This is a demo of passing data from controller to view.'
];

3. Load the view and pass the data to it using the view() method:

return view('welcome_message', $data);

In this example, we’re loading a view named “welcome_message” and passing the $data array to it. In the view, we can access the data using the array keys, for example:

<h1><?php echo $title; ?></h1>
<p><?php echo $message; ?></p>
