What are the best practices for ensuring that only authenticated users can access files in a protected directory using PHP?

To ensure that only authenticated users can access files in a protected directory using PHP, you can implement user authentication and authorization checks before allowing access to the files. This can be done by checking if the user is logged in and has the necessary permissions to view the files. Additionally, you can use sessions or tokens to track user authentication status. 

<?php
session_start();

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

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

// Access files in protected directory
// Your code to access files here
?>
