How to fix Call to a member function result() on a non-object in?

Question

CodeIgniter

Good day.
I am using codeigniter framework in php. This is the situation:
In the controller:

$data_app = array(
      'key_api' => substr(md5(uniqid(rand(), true)), 0, 22)
    );
    
    $data['app'] = $data_app;
    $this->load->view('apps/new', $data);

In display:

<?php foreach ($app->result() as $data): ?>
<?= $data->key_api; ?>
<?php endforeach; ?>

*Yeah, tagging mess, I know, just for example*
Fatal error: Call to a member function result() on a non-object in.
I don't understand, because we created an array. And the result() method converts it to an array of objects. Why error?
Thanks in advance.

Answer 1

$app is an array, not an object! where does it get the result() method from?
This is exactly what the error tells you that you are trying to call the result () method from a non-object.

Answer 2

result() operates on data retrieved from the database. You wrote nonsense here. You created an array, and work with the variable as an array.
