How can display_errors and error_reporting settings impact debugging PHP scripts, especially when uploading files?

Display_errors and error_reporting settings impact debugging PHP scripts by controlling whether errors are displayed to the screen and the level of detail provided. When uploading files, it is crucial to have error messages displayed to catch any issues that may arise during the process. Setting display_errors to On and error_reporting to E_ALL can help ensure that all errors are shown, making it easier to identify and fix any problems.

// Enable error reporting and display errors
ini_set('display_errors', 1);
ini_set('error_reporting', E_ALL);
