class Logger { // Logger implementation } $logger = new Logger(); Registry::set('logger', $logger);
class CustomerService { public function handleOrder($orderId) { $logger = Registry::get('logger'); $logger->log("Order processed: " . $orderId); } }In this example, we retrieve the Logger object stored in the Registry using the get method and use it to log the order processing event. The PHP Registry pattern is not a specific package library. It is a design pattern used in software engineering to provide an alternative to global variables for storing objects across the application.
