codeigniter abort 404

To handle 404 errors in CodeIgniter, follow these steps:

  1. Create a custom 404 error page by creating a new file named "404.php" in the "application/views/errors" directory.

  2. Edit the "application/config/routes.php" file and add a route to redirect 404 errors to your custom 404 error page using the following code:

$route['404_override'] = 'errors/custom_404';
  1. Create a new controller named "Errors" in the "application/controllers" directory and define a method named "custom_404" to load the custom 404 error page.
