How can hidden fields be effectively used in PHP forms to manage data deletion without unintended consequences?

Hidden fields can be effectively used in PHP forms to manage data deletion by including a unique identifier for the data to be deleted in the form as a hidden field. This identifier can then be used to target the specific data for deletion upon form submission. By using hidden fields, you can ensure that only the intended data is deleted without any unintended consequences. 

```php
<form method="post" action="delete.php">
    <input type="hidden" name="id" value="<?php echo $data_id; ?>">
    <input type="submit" value="Delete">
</form>
```

In the above code snippet, a hidden input field named "id" is included in the form with the value set to the unique identifier of the data to be deleted. Upon form submission, the "delete.php" script can retrieve this identifier from the hidden field and use it to delete the specific data without any unintended consequences.
