What steps can be taken to troubleshoot and debug PHP scripts that are not displaying errors?
If PHP scripts are not displaying errors, one possible solution is to check the PHP configuration settings to ensure that error reporting is enabled. This can be done by setting the `display_errors` and `error_reporting` directives in the php.ini file. Additionally, you can manually enable error reporting within the script using the `error_reporting` function.
```php
// Enable error reporting in PHP script
error_reporting(E_ALL);
ini_set('display_errors', 1);
```
This code snippet will enable error reporting in the PHP script, allowing any errors to be displayed on the screen.
