What are the best practices for combining navigation and text content in PHP to display specific content on different pages?

When combining navigation and text content in PHP to display specific content on different pages, it is best practice to use conditional statements to determine which content to display based on the page being accessed. This can be achieved by passing a parameter in the URL or using session variables to track the current page. By organizing your content and navigation links effectively, you can create a seamless user experience.

<?php
// Check which page is being accessed
if(isset($_GET['page'])) {
    $page = $_GET['page'];
} else {
    $page = 'home';
}

// Display content based on the page
switch($page) {
    case 'home':
        echo "Welcome to the homepage!";
        break;
    case 'about':
        echo "Learn more about us.";
        break;
    case 'contact':
        echo "Contact us for more information.";
        break;
    default:
        echo "Page not found.";
}
?>
