What are the key considerations when structuring PHP code to support dynamic content loading in a web application?

When structuring PHP code to support dynamic content loading in a web application, key considerations include separating the presentation layer from the business logic, using templates to easily swap out content, utilizing AJAX to load content dynamically without refreshing the page, and implementing a clean and modular code structure for easy maintenance and scalability. 

// Example PHP code snippet for dynamic content loading using AJAX

// index.php
<!DOCTYPE html>
<html>
<head>
    <title>Dynamic Content Loading</title>
    <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
</head>
<body>
    <div id="content"></div>
    <button id="loadContent">Load Content</button>

    <script>
        $(document).ready(function(){
            $('#loadContent').click(function(){
                $.ajax({
                    url: 'load_content.php',
                    type: 'GET',
                    success: function(response){
                        $('#content').html(response);
                    }
                });
            });
        });
    </script>
</body>
</html>

// load_content.php
<?php
// This is where you would fetch dynamic content from a database or API
$content = "This is dynamically loaded content.";

echo $content;
?>
