How can the issue of including unnecessary "1" at the end of a file included using include() be resolved in PHP scripts?

The issue of including an unnecessary "1" at the end of a file included using include() can be resolved by ensuring that there is no whitespace or output after the closing PHP tag in the included file. This can be achieved by removing any closing PHP tag ?> and any whitespace after it in the included file. 

```php
<?php
include('file.php');
```

In the included file 'file.php', ensure that there is no closing PHP tag ?> or any whitespace after it. This will prevent the "1" from being included at the end of the file.
