Drupal: Show Erros on Developing or WSOD

In Drupal while developing it not showing the errors instead of it will be showing us a White screen. This screen is known as White Screen Of Death(WSOD). During development, we need to debug the errors, for this purpose we want to show errors. To show errors instead or white screen we need to add below lines in "settings.php".


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