Talk:Registry

While the registry is often implemented as a singleton, I don't think there's any steadfast rules that this need to be the case. If the registry is created and passed in the constructor to the objects, that need it, the static-nature is remedied. In this incarnation, the registry is a very powerful pattern.

I agree and welcome the comment. While there are varying methods of implementing the Registry, its core purpose does not depend on any specific implementation. A Registry can be accessed as a Singleton, by Parameter or as a static method. The Zend Framework for example has static register()/registry() methods in Zend.php. There are many other examples of broadly different implementations.

I'll revisit the article in the near future to note all these variations and be more clear on separating a specific implementation from the core pattern.

As an aside - feel free to make comments on the Forum for corrections and such. These Talk pages aren't checked all that often in comparison. Thanks for the comment!

Sometimes we need all the data stored in Registry. I prefer dumping the data with __sleep() magic method. Loading back could be done by instantiating a new Registry object also:

class Registry {
 
  private $store = array();
 
  function __construct($store = NULL) {
    $this->load($store);
  }
 
  function load($store = NULL) {
    if (is_array($store) && count($store))
      $this->store = $store;
  }
 
  function __sleep() {
    return $this->store;
  }
 
  ...
}
