How can PHP developers prevent unauthorized access to user accounts by implementing secure session management practices?

To prevent unauthorized access to user accounts, PHP developers can implement secure session management practices such as using HTTPS, setting secure session cookies, regenerating session IDs, and validating session data on each request. 

// Start a secure session
session_start([
    'cookie_lifetime' => 86400, // Session cookie expires in 1 day
    'cookie_secure' => true, // Cookie will only be sent over HTTPS
    'cookie_httponly' => true, // Cookie is only accessible via HTTP protocol
]);

// Regenerate session ID to prevent session fixation attacks
session_regenerate_id(true);

// Validate session data on each request
if (!isset($_SESSION['user_id'])) {
    // Redirect to login page if user is not authenticated
    header("Location: login.php");
    exit();
}
