drupal 8 show php errors settings.php

To show PHP errors in Drupal 8's settings.php file, you can add the following code:

error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);

This code sets the error reporting level to display all errors, and enables the display of errors and startup errors.

Please note that it's important to disable error display in a production environment for security reasons. It's recommended to only enable error display in a development or testing environment.
