I once remembered that Brother Laruence mentioned that it was not recommended to use "magic methods." 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. Let’s first take a look at what Bird Brother Laruence once mentioned on his blog: When I share the PPT with my colleagues in the company, some people will question it, saying that magic methods are not allowed to be used?

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.
