How can PHP users effectively utilize include(), IF/ELSE statements, and basic PHP knowledge to create dynamic page loading?

To create dynamic page loading in PHP, users can utilize the include() function to load different content based on certain conditions using IF/ELSE statements. By organizing different sections of a webpage into separate files and including them dynamically, users can easily update and manage their website's content. This approach also allows for better code reusability and maintenance.

<?php
$page = isset($_GET['page']) ? $_GET['page'] : 'home';

if($page == 'home'){
    include('home.php');
} elseif($page == 'about'){
    include('about.php');
} elseif($page == 'contact'){
    include('contact.php');
} else {
    include('404.php');
}
?>
