How can PHP beginners positively utilize the inclusion of specific PHP files based on parameters in URLs?

Beginners can utilize the inclusion of specific PHP files based on parameters in URLs by using conditional statements to check the parameter value and then including the corresponding PHP file. This allows for dynamic loading of different files based on the URL parameters, providing a flexible way to organize and display content on a website.

<?php

// Check if a parameter is set in the URL
if(isset($_GET['page'])) {
    // Include the corresponding PHP file based on the parameter value
    $page = $_GET['page'];
    if($page == 'home') {
        include 'home.php';
    } elseif($page == 'about') {
        include 'about.php';
    } elseif($page == 'contact') {
        include 'contact.php';
    } else {
        include '404.php'; // Page not found
    }
} else {
    include 'home.php'; // Default page
}

?>
