What are the best practices for handling different versions of a webpage in PHP without using multiple HTML files?

When handling different versions of a webpage in PHP without using multiple HTML files, a common approach is to use conditional statements to dynamically generate content based on the version requested by the user. This can be achieved by using URL parameters, session variables, or any other method of identifying the version. By using PHP to dynamically generate the content, you can maintain a single HTML file while still serving different versions of the webpage. 

<?php

// Determine the version of the webpage requested
$version = isset($_GET['version']) ? $_GET['version'] : 'default';

// Use conditional statements to generate content based on the version
if ($version == 'version1') {
    // Content for version 1
    echo '<h1>Welcome to Version 1</h1>';
} elseif ($version == 'version2') {
    // Content for version 2
    echo '<h1>Welcome to Version 2</h1>';
} else {
    // Default content
    echo '<h1>Welcome to the Default Version</h1>';
}

?>
