How can data attributes be effectively utilized in PHP to enhance interactivity and styling?

To enhance interactivity and styling in PHP, data attributes can be effectively utilized. Data attributes allow developers to store extra information within HTML elements, which can then be accessed and manipulated using JavaScript or CSS. This can be particularly useful for dynamically updating content, applying styles based on specific data values, or triggering interactive elements based on data attributes.

```php
<div class="element" data-value="123">Example Element</div>
```

In the above code snippet, a data attribute "data-value" is added to a div element with a value of "123". This data attribute can be accessed and manipulated using JavaScript or CSS to enhance interactivity and styling on the webpage.
