works in a large code base. This article does not show large applications, so what you need to think about is how to apply the principle of the example in your own large application-not the code that this article demonstrates. This is not to say that you should not use patterns in small applications. Many good applications start with small applications and evolve to large applications, so there is no reason not to build on such solid coding practices

provides loosely coupled, or that you are writing a pattern named Observer. It is very difficult to demonstrate the value of a pattern with a smaller example. This is often a bit of an overkill, because the pattern actually works in a large code base.

The design pattern is only prepared for the Java architect-at least you may always think so. In fact, the design pattern is very useful to everyone. If these tools are not the patents of the "architecture astronauts", what are they? Why are they very useful in PHP applications? This article explains these problems Design

Please read the previous article first Refactoring Even the most thoughtful and skilled programmers cannot foresee any nuance in a software project. The problem is always unexpected, the demand may be changing, and the result is that the code is optimized, shared, and replaced. Refactoring is a common approach: check all your code to find the similarities and the similarities in which you can unify and simplify, making your code easier to maintain and extend. Refactoring also involves exploring
implementation change, Concretevisitor also increases the corresponding behavior, Gof suggests that it is better to define actions individually in these object classes without using the visitor design pattern. Iv. Visitor mode and other modes 1. If the structure object being browsed is linear, it is possible to use an iterative mode instead of a visitor pattern2, visitor mode to browse some of the structural objects of the composite modeAbove two p
