How can PHP be used to create a secure area for visitors to access downloadable content?

To create a secure area for visitors to access downloadable content, you can use PHP to authenticate users before allowing them to download files. This can be achieved by storing user credentials in a database, checking the credentials when a user tries to access the download page, and only allowing access if the user is authenticated. 

<?php
session_start();

// Check if user is logged in
if(!isset($_SESSION['loggedin'])) {
    header('Location: login.php');
    exit;
}

// Check if the user has the necessary permissions to access the download page
if($_SESSION['role'] != 'admin') {
    echo "You do not have permission to access this page.";
    exit;
}

// Provide download link to authorized users
echo "<a href='download_file.php'>Download File</a>";
?>
