How can error_reporting and display_errors settings help in debugging PHP scripts, especially when dealing with file uploads?

When dealing with file uploads in PHP scripts, setting the error_reporting and display_errors settings can help in debugging by providing detailed error messages about any issues that may arise during the file upload process. This can help identify any potential problems such as file size limits, file type restrictions, or permission issues that may be causing the file upload to fail.

// Set error reporting and display errors settings for debugging file uploads
error_reporting(E_ALL);
ini_set('display_errors', 1);
