Abstract factory pattern is used when we need multiple factories which produce related but different sets of objects. This pattern is generally used in relatively larger applications that deal with lots of classes of related classes but can be divided into multiple groups based on some criteria. This article discusses the Abstract Factory pattern implementations in PHP.
Factory pattern helps to separate the creator of the objects from the object classes. The creator/factory is responsible for generating objects. Factory implementation process is not strict or predefined. The implementation depends on how we want to identify different objects and generate those. In this article we are demonstrating the Factory pattern implementation in PHP programming language.
Singleton pattern is used to ensure that only one instance of a class is created in any case, and whenever you want to get an instance of that class, then the same object instance is returned.
