session_start(); // Start user session $_SESSION['user_id'] = 123; // Set user ID in session
if ($username == "john" && $password == "secret") { // Valid user credentials } else { // Invalid user credentials }
if ($_SESSION['user_role'] == "admin") { // User is authorized } else { // User is not authorized }In this example, we check the user role stored in the session variable and determine if the user is authorized to perform certain actions. Conclusion: The PHP User Init package/library provides essential functions for user authentication and authorization. This package can be used in conjunction with other PHP frameworks or standalone applications to manage user sessions and access control.
