Since then, whenever magic methods are used, I will subconsciously think about it, is this a good way to take photos? Since I have been busy with work and learning new knowledge in the past one to two years, I have not done any in-depth exploration on this road and it has been in a daze. This year is a year for me to study in depth, so now I must do some research on this issue. The problem is settled.

If you can be aware of what is slow and what is fast when writing code, thereby avoiding unnecessary calls to magic methods, that is the effect pursued by this optimization suggestion. Doubt the real performance of magic methods. Is it worse? Is there still a problem with the performance of using magic methods in PHP7? How should we use magic methods reasonably? Solution Faced with my doubts, my solution is: statistically compare the difference in script execution time between using magic methods and not using magic methods PHP5.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
