What are the PHP design patterns?

According to purpose, there are currently 23 common PHP design patterns, which can be divided into the following three categories according to different usage goals:

Creational Patterns (5 types):

Design patterns used when creating objects. More specifically, the design pattern of the initialization object process. As programs become more complex, objects need to be created more flexibly while reducing dependencies during creation. Creating design patterns is a type of design pattern that solves this problem.

Single case mode [Singleton]

Factory mode[Factory]

Abstract factory mode[ AbstractFactory】

Builder Mode【Builder】

Prototype Mode【Prototype】

Structural Design Patterns (7 types):

Design patterns used for inheritance and interfaces. The structural design pattern is used to design function methods of new classes, reducing unnecessary class definitions and reducing code redundancy.

Adapter mode [Adapter]

Bridge mode [Bridge]

Composite mode [Composite]

Decorator mode [Decorator]

Facade Mode【Facade】

Proxy Mode【Proxy】

Flyweight Mode【Flyweight】

Behavioral Patterns (11 types):

Design patterns used for method implementation and corresponding algorithms, and are also the most complex design patterns. Behavioral design patterns are not only used to define the functional behavior of classes, but also for protocols and communications between different classes.

Strategy Mode【Strategy】

Template Method Mode【TemplateMethod】

Observer Mode【Observer】

Iterator Mode【Iterator】

Responsibility Chain Mode【ResponsibilityChain】

Command Mode【Command】

Memo Mode【Memento】

State Mode【State】

Visitor Mode【Visitor】

Mediator Mode【Mediator】

Interpreter Mode【Interpreter】
