It seems that all design patterns are designed so that the program has low coupling, high flexibility, good expansibility, clear program structure and so on. Today's design pattern-the observer pattern is no exception, but the clarity of the program structure may not be the point. Well, the nonsense is less, the pattern of this simple and rude things still have t

sometimes referred to as static factories. In order to select the implementation, you can also configure the selected parts to the configuration file.

Object-oriented design is a very important part of PHP program development, if you want to be a senior PHP programmer, we must know the specific usage and wording of object-oriented design. Maintaining a simple modularity is a fe

61 empirical principles of Object-Oriented Design Excerpted from the log of OOD, translated by BaO zhiyun, Arthur J.

If you violate one of them, the warning bells wi

In Ood (object-oriented design), abstract classes or interfaces are often used, "note: in C + +, there is no concept of interfaces, only abstract classes, and both exist in Java." In the process of use, there may be many people think that the interface and abstract class is similar, and then think of course that can be completely replaced with each other. In fact

derived class. p103(53) Do not confuse the optional inclusion with the need for inheritance. Modeling an optional inclusion into a class where inheritance can lead to flooding. p108(54) When creating an inheritance hierarchy, try creating a reusable framework, rather than a reusable component. p112(55) If you use multiple inheritance in your design, let's say you made a mistake. If you don't make a mistake, you need to try to prove it. P120(56) If yo

Arthur J.riel once said that you do not have to strictly abide by these principles and will not be sentenced to religious punishment for violating them. But you should think of these principles as alarms, and if you violate one of them, the alarm will ring. So, whatever we do, we have to have a principle. Programming is no exception, the following describes PHPThe principle of object-oriented analysis
