Are there best practices for handling sessions in PHP to ensure security?

To ensure security when handling sessions in PHP, it is important to use best practices such as regenerating session IDs, setting secure session cookie parameters, and validating session data to prevent session hijacking and other attacks. 

// Start session
session_start();

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

// Set secure session cookie parameters
session_set_cookie_params([
    'lifetime' => 0,
    'path' => '/',
    'domain' => 'example.com',
    'secure' => true,
    'httponly' => true
]);

// Validate session data before using it
if(isset($_SESSION['user_id'])){
    // Proceed with using session data
} else {
    // Handle unauthorized access
}
