As a PHP developer, know that many programmers have despised PHP, why? Because they think PHP syntax is dirty, and because of the uneven level of developers, PHP code is more chaotic, maintenance is almost a lump of shit. As PHP joined the object-oriented formation, many developers began to use OOP ideas to write code, and PHP became more and more standard and more standardized. And the design pattern plays a very important role. Recently, the boss to

add a user, you need to rewrite the code. Using the policy mode, if you add a new user type, you only need to add one more policy. All other places just need to use a different strategy.The interface file for the policy is declared first, and the contained behavior of the policy is contracted. Then, define each specific policy implementation class.Example:PHP//declares the interface of the policy file, and the behavior that the contract policy contains.

Strategy Mode of design patternLearning:http://blog.csdn.net/hguisu/article/details/7558249/1. What is a policy model?In software development also often encounter similar situation, to achieve a certain function has a number of algorithms or strategies, we can choose different algorithms or strategies according to the environment or conditions to complete the function . the

care. The context selects specific policy algorithms. This will be demonstrated later when we talk about fault tolerance recovery. (5) implementation of strategyIn the previous example, strategy is defined by interfaces, which is also a common implementation method. However, if multiple algorithms have public functions, You can implement strategy as an abstract class, and then implement the public functi

Problem Analysis: The role should be able to change weapons dynamically. In the future, other roles or other types of weapons may be added. according to the principle of "Separating variable parts and encapsulating them separately", wea

different times of the system, the same system may be in different business modes, so it is necessary to analyze the business application at the peak of the system. The goal is to determine whether the peak business application model is a single business type or a hybrid business type by analyzing peak applications, which is critical to the design of the late test case execution strategy. For example, many
