Answer 1

You can use Component, they are stored in Controller/Component/

For example if you have Controller/Component/SomeComponent.php and want call it on the fly in single action inside controller:

$this->SomeComponent = $this->Components->load('SomeComponent');
$this->SomeComponent->someFunction();
