Custom view method

In CI3, I created a custom view method (cView) by extending CI_Loader :

// My controller, log user data and search queries
class MY_Loader extends CI_Loader
{
    public function __construct()
    {
        parent::__construct();
    }
   
    // Custom view loader, load and return the view if display is true
    public function cView($view, $vars = array(), $display = TRUE)
    {
        if (!$display) return '';
        return $this->view($view, $vars, TRUE);
    }
}

Since CI_Loader and the core folder no longer exist, I can't figure out where I should create my custom cView function in CI4? The main constrain is that cView() calls the native view() method.

Here are the complete code for view. You can create your own cView and put in in app/Common.php based on that. Or overwrite the system function.

PHP Code:

if (! function_exists('view'))
{
    /**
     * Grabs the current RendererInterface-compatible class
     * and tells it to render the specified view. Simply provides
     * a convenience method that can be used in Controllers,
     * libraries, and routed closures.
     *
     * NOTE: Does not provide any escaping of the data, so that must
     * all be handled manually by the developer.
     *
     * @param string $name
     * @param array  $data
     * @param array  $options Unused - reserved for third-party extensions.
     *
     * @return string
     */
    function view(string $name, array $data = [], array $options = []): string
    {
        /**
         * @var CodeIgniter\View\View $renderer
         */
        $renderer = Services::renderer();

        $saveData = config(View::class)->saveData;

        if (array_key_exists('saveData', $options))
        {
            $saveData = (bool) $options['saveData'];
            unset($options['saveData']);
        }

        return $renderer->setData($data, 'raw')
                        ->render($name, $options, $saveData);
    } 


Here are the complete code for view. You can create your own cView and put in in app/Common.php based on that. Or overwrite the system function.

Thank for the answer, if I want to overwrite the system function, where should I put the code ?

In app/Common.php, as it's loaded first.

Thank you to all of you for these answers. I finally place my custom view in the BaseController since I use it everywhere in my apps: https://forum.codeigniter.com/thread-75176.html
