How can developers effectively handle session management in PHP to prevent unauthorized access and maintain user security?

Developers can effectively handle session management in PHP by using secure session handling techniques such as regenerating session IDs, setting appropriate session configuration options, and validating session data on each request. This helps prevent unauthorized access and maintain user security. 

// Start session
session_start();

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

// Set session configuration options for increased security
ini_set('session.cookie_httponly', 1);
ini_set('session.use_only_cookies', 1);

// Validate session data on each request
if (!isset($_SESSION['authenticated']) || $_SESSION['authenticated'] !== true) {
    // Redirect to login page or deny access
    header('Location: login.php');
    exit;
}
