How can AJAX be effectively used to interact with PHP classes for dynamic website functionalities like live search?

To interact with PHP classes for dynamic website functionalities like live search using AJAX, you can create a PHP script that handles the search functionality and returns the results in JSON format. Then, use AJAX to send search queries to this PHP script, receive the results, and update the webpage dynamically without refreshing the page. 

```php
// search.php

// Include the necessary PHP classes
require_once 'SearchClass.php';

// Get the search query from the AJAX request
$searchQuery = $_GET['query'];

// Create an instance of the SearchClass
$search = new SearchClass();

// Perform the search using the search query
$results = $search->search($searchQuery);

// Return the results in JSON format
echo json_encode($results);
```
In the above PHP code snippet, we have a `search.php` script that handles the search functionality. It includes a `SearchClass.php` file that contains the PHP class for searching. The script receives the search query from the AJAX request, creates an instance of the `SearchClass`, performs the search, and returns the results in JSON format. This script can be called using AJAX to implement live search functionality on a webpage.
