What are the best practices for managing user sessions and authentication in PHP to control access to specific content?

To manage user sessions and authentication in PHP, it is essential to use secure methods to control access to specific content. This can be achieved by implementing a login system with user authentication, storing session data securely, and validating user permissions before granting access to restricted content. 

<?php
session_start();

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

// Check user permissions before accessing restricted content
if($_SESSION['user_role'] !== 'admin') {
    echo "You do not have permission to access this content.";
    exit();
}

// Access restricted content here
echo "Welcome, Admin!";
?>
