How can errors in PHP files be displayed with line numbers in a non-XAMPP environment?

To display errors in PHP files with line numbers in a non-XAMPP environment, you can set the error_reporting level to include E_ALL and then enable the display_errors directive in your php.ini file. This will show errors with line numbers directly in the browser when they occur.

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

// Enable displaying errors in the browser
ini_set('display_errors', 1);
