php display errors

Open the "index.php" file in the root directory of your CodeIgniter application.

Locate the following line of code: php define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'development');

Change the value of the 'ENVIRONMENT' constant to 'development' to enable error display: php define('ENVIRONMENT', 'development');

Find the following code block in the same "index.php" file: ```php if (defined('ENVIRONMENT')) { switch (ENVIRONMENT) { case 'development': error_reporting(-1); ini_set('display_errors', 1); break;

   case 'testing':
   case 'production':
       ini_set('display_errors', 0);
       if (version_compare(PHP_VERSION, '5.3', '>='))
       {
           error_reporting(E_ALL & ~E_NOTICE & ~E_DEPRECATED & ~E_STRICT & ~E_USER_NOTICE & ~E_USER_DEPRECATED);
       }
       else
       {
           error_reporting(E_ALL & ~E_NOTICE & ~E_STRICT & ~E_USER_NOTICE);
       }
       break;

   default:
       exit('The application environment is not set correctly.');

} } ```

Ensure that the 'development' case is configured to display errors: php case 'development': error_reporting(-1); ini_set('display_errors', 1); break;

Save the changes to the "index.php" file.

Refresh your CodeIgniter application in the web browser to see the displayed errors.
