How can JavaScript values be preserved when interacting with PHP functions in a dynamic data display scenario?

When interacting with PHP functions in a dynamic data display scenario, JavaScript values can be preserved by passing them as parameters to the PHP functions through AJAX requests. This allows the JavaScript values to be sent to the server-side PHP code, processed, and returned back to the client-side JavaScript for display without losing their original values. 

// JavaScript code to send AJAX request with JavaScript values to PHP function
$.ajax({
    url: 'process_data.php',
    type: 'POST',
    data: { js_value: js_value },
    success: function(response) {
        // Handle the response from PHP function
    }
});
```

```php
// PHP code in process_data.php to receive JavaScript values and process them
$js_value = $_POST['js_value'];

// Process the JavaScript value and return the result
$result = some_php_function($js_value);

echo $result;
