Editor to share with you how to use the factory pattern in the php design pattern. I hope you will get something after reading this article. Let's discuss it together.

Function: encapsulation of object creation, simplifying the operation of creating objects, that is, calling a method of the factory class to get the desired class

Add:

1. Main roles: abstract product (Product), concrete product (Concrete Product), abstract factory role (Creator)

Advantages: the factory method model allows the system to introduce heart products without modifying the factory role

3. Applicability

When a class does not know the objects it must create

When a class wants its subclasses to determine the objects it creates

When a class delegates the responsibility of creating an object to one of several help subclasses, and you want you to localize the information about which help subclass is a proxy

The copy code is as follows:
