Introduction to the introduction of PHP design Patterns When you're constantly trying to discover new features from your application, do you find that the solution you're proposing is similar to something you've already implemented in the past? If you are a programmer (even if you start a short time), you may be able to answer "yes". It seems that you have used some of the previous code to solve the new p

In order to embrace this unknown change at the lowest cost, our predecessors summed up so many principles. ① Yagni PrinciplesYou aren ' t gonna need itDo not write code that you do not need②kiss PrinciplesKeep it simple and stupidCode keepin
