// Get the instance of Zend_Auth $auth = Zend_Auth::getInstance(); // Use the authenticate method to validate the user credentials $result = $auth->authenticate($adapter);
// Get the instance of Zend_Auth $auth = Zend_Auth::getInstance(); // Check if a user is authenticated if ($auth->hasIdentity()) { // User is authenticated, get the user info $user = $auth->getIdentity(); } else { // User is not authenticated, redirect to the login page header('Location: login.php'); exit; }In this example, we use the hasIdentity method to check if a user is authenticated. If the user is authenticated, we get the user info using the getIdentity method. If the user is not authenticated, we redirect them to the login page. Overall, Zend_Auth is a useful package library for implementing authentication and authorization in PHP applications. The getInstance method is a helpful tool for getting an instance of the class and using it throughout your application.
