What are the benefits of using jQuery for autocomplete features in PHP applications?

When implementing autocomplete features in PHP applications, using jQuery can greatly enhance the user experience by providing real-time suggestions as the user types in a text input field. jQuery simplifies the process of making AJAX requests to fetch data from the server and updating the UI dynamically. This can help reduce server load and improve the overall performance of the application. 

```php
// PHP code snippet for autocomplete feature using jQuery

<?php
// Assume $data is an array of suggestions fetched from a database

if(isset($_GET['query'])){
    $query = $_GET['query'];
    $results = array();

    foreach($data as $item){
        if(stripos($item, $query) !== false){
            $results[] = $item;
        }
    }

    echo json_encode($results);
}
?>
```

This PHP code snippet demonstrates how to handle AJAX requests for autocomplete suggestions. The server-side script receives a query parameter, filters the data based on the query, and returns the matching results in JSON format. This data can then be processed by jQuery on the client-side to update the autocomplete suggestions dynamically.
