// Load the User model class using ClassRegistry $this->User = ClassRegistry::init('User');
// Lazily load a Session component using ClassRegistry $session = ClassRegistry::getObject('Session'); if (!$session) { $session = ClassRegistry::init('Session'); ClassRegistry::addObject('Session', $session); }In this example, ClassRegistry is used to lazily load a Session component object. If the object has not yet been instantiated, the code retrieves it using ClassRegistry::init(), creates a new instance, and adds it to the registry using ClassRegistry::addObject(). Package/Library: ClassRegistry is a part of the CakePHP framework, which is a popular web development framework for PHP. It is included in the core library of CakePHP, and can be used in any CakePHP application without any additional installation or configuration.
