Are there any best practices for organizing PHP code to handle dynamic content loading based on user actions?

When handling dynamic content loading based on user actions in PHP, it is best practice to use AJAX to asynchronously fetch and update content without reloading the entire page. This allows for a smoother user experience and reduces server load. Organizing your PHP code into separate files for handling different types of requests can help keep your codebase clean and maintainable. 

// index.php
<!DOCTYPE html>
<html>
<head>
    <title>Dynamic Content Loading</title>
    <script src="https://code.jquery.com/jquery-3.5.1.min.js"></script>
</head>
<body>
    <div id="content"></div>
    
    <script>
        $(document).ready(function(){
            $('#content').load('initial_content.php');
            
            $('#button').click(function(){
                $('#content').load('updated_content.php');
            });
        });
    </script>
</body>
</html>
```

```php
// initial_content.php
<?php
echo "Initial content loaded.";
?>
```

```php
// updated_content.php
<?php
echo "Updated content loaded.";
?>
