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. <?php
$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.
