How can PHP error reporting be configured to ensure that all errors, including file operation errors, are displayed for easier troubleshooting?

To ensure that all errors, including file operation errors, are displayed for easier troubleshooting in PHP, you can configure the error reporting level in your PHP script. This can be achieved by setting the error_reporting function to E_ALL, which will display all types of errors including file operation errors.

// Set error reporting level to display all errors
error_reporting(E_ALL);
