What are the advantages and disadvantages of using AJAX to update the menu styling based on user interactions in a PHP website?

Issue: The menu styling in a PHP website needs to be updated based on user interactions. Using AJAX can help achieve this without refreshing the entire page, providing a seamless user experience. However, it may increase the complexity of the code and require additional server-side processing. 

// PHP code snippet using AJAX to update menu styling based on user interactions

// HTML/PHP code for menu
<div id="menu">
  <ul>
    <li><a href="#" id="menu-item-1">Item 1</a></li>
    <li><a href="#" id="menu-item-2">Item 2</a></li>
    <li><a href="#" id="menu-item-3">Item 3</a></li>
  </ul>
</div>

// JavaScript code to handle AJAX request
<script>
  $(document).ready(function(){
    $('#menu-item-1').click(function(){
      $.ajax({
        url: 'update_menu_style.php',
        type: 'POST',
        data: { menu_item: '1' },
        success: function(response){
          // Update menu styling based on response
        }
      });
    });
  });
</script>

// PHP code in update_menu_style.php
<?php
$menu_item = $_POST['menu_item'];

// Update menu styling based on $menu_item
// Return response
