What are potential reasons for a PHP script to end without displaying an error message?

One potential reason for a PHP script to end without displaying an error message is that error reporting may be turned off in the PHP configuration settings. To solve this issue, you can enable error reporting in your PHP script by adding the following line at the beginning of your script:

```php
error_reporting(E_ALL);
```

This will ensure that all errors, warnings, and notices are displayed, helping you identify any issues in your script.
