Without culture, and the relative freedom it implies, society, even when perfect, is but a jungle. This is why any authentic creation is a gift to the future.
If the Lord Almighty had consulted me before embarking on creation thus, I should have recommended something simpler.
Creational design patterns are those that focus on the instantiation process. These patterns are designed to conceal the creation process from the instances created and encapsulate knowledge used by the objects. The five creational design patterns listed by Gamma, Helm, Johnson, and Vlissides include:
Abstract Factory
Builder
Factory Method
Prototype
Singleton
Of these five, the Factory Method and Prototype have been selected
as examples of creational designs implemented in PHP. The Factory Method
is the only one of the five that is included in the class scope category
of design patterns, and it is a relatively simple yet informative pattern.
The Prototype pattern is in the object category, and it can be implemented
using the PHP __clone()
method. Objects
are instantiated (created) on the basis of prototype, and then further
objects are cloned from the instantiated object. I think you will find
this pattern easy to use and quite handy.
Of the uses of creational patterns, the most interesting is that ...
