What are some best practices for error reporting and debugging in PHP scripts, especially when no error messages are displayed?

When error messages are not displayed in PHP scripts, it can be challenging to identify and debug issues. One common approach is to enable error reporting and display errors in the PHP configuration settings. This can be done by setting the `display_errors` and `error_reporting` directives in the php.ini file or within the script using `ini_set()` function. Additionally, using debugging tools like Xdebug or incorporating logging mechanisms can help in tracking and resolving errors effectively.

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