What are best practices for displaying PHP error messages in a production environment?

Displaying PHP error messages in a production environment can pose security risks by exposing sensitive information about your code. To prevent this, it is recommended to log errors to a file instead of displaying them to the user. This way, you can still track and troubleshoot errors without compromising the security of your application.

// Set error reporting level to log errors only
ini_set('display_errors', 0);
ini_set('log_errors', 1);
ini_set('error_log', '/path/to/error.log');
