What are the best practices for dynamically generating pages using PHP to avoid the need for manual file creation?

When dynamically generating pages using PHP, it is best to use a combination of URL rewriting and a single PHP script to handle different page requests. By using URL rewriting, you can pass parameters in the URL to determine which content to display, allowing you to avoid the need for manually creating individual files for each page. This approach streamlines the process and makes it easier to manage and update content on the website.

// .htaccess file for URL rewriting
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]

// index.php script to handle dynamic page generation
<?php
if(isset($_GET['url'])) {
    $url = $_GET['url'];
    
    // logic to determine which content to display based on the URL parameter
    switch($url) {
        case 'about':
            include 'about.php';
            break;
        case 'contact':
            include 'contact.php';
            break;
        default:
            include '404.php';
            break;
    }
} else {
    include 'home.php';
}
?>
