Final class Phalcon\Registry

implements ArrayAccess, Iterator, Traversable, Serializable, Countable, JsonSerializable

A registry is a container for storing objects and values in the application space. By storing the value in a registry, the same object is always available throughout your application.

$registry = new \Phalcon\Registry();

      // Set value
      $registry->something = 'something';
      // or
      $registry['something'] = 'something';

      // Get value
      $value = $registry->something;
      // or
      $value = $registry['something'];

      // Check if the key exists
      $exists = isset($registry->something);
      // or
      $exists = isset($registry['something']);

      // Unset
      unset($registry->something);
      // or
      unset($registry['something']);

In addition to ArrayAccess, Phalcon\\Registry also implements Countable (count($registry) will return the number of elements in the registry), Serializable and Iterator (you can iterate over the registry using a foreach loop) interfaces. For PHP 5.4 and higher, JsonSerializable interface is implemented.  Phalcon\\Registry is very fast (it is typically faster than any userspace implementation of the registry); however, this comes at a price: Phalcon\\Registry is a final class and cannot be inherited from.  Though Phalcon\\Registry exposes methods like __get(), offsetGet(), count() etc, it is not recommended to invoke them manually (these methods exist mainly to match the interfaces the registry implements): $registry->__get('property') is several times slower than $registry->property.  Internally all the magic methods (and interfaces except JsonSerializable) are implemented using object handlers or similar techniques: this allows to bypass relatively slow method calls.
