What are best practices for debugging PHP code that is not displaying any output?

If your PHP code is not displaying any output, it could be due to errors in the code that are not being displayed. To debug this issue, you can enable error reporting in PHP to see any errors that are occurring. You can do this by adding the following line at the beginning of your PHP script: 

```php
error_reporting(E_ALL);
ini_set('display_errors', 1);
```

This will display any errors that are preventing your code from executing properly.
