1. Safety
No matter how the program is written, safety is the first priority. Programs without safety guarantees cannot be of high quality.
2. Stability
No matter how bad your code is, it must run stably.
3. User experience
User experience directly determines the fate of a program. It is impossible to talk about the high quality of a program that does not understand user experience at all.
4. Business experience
The purpose of developing applications is naturally to make money. I think that no matter how excellent a program is, it is a waste if it does not make money.
5. Efficiency
This is the last one. I have always believed that performance is the most secondary. The efficiency of the PHP program itself is not too high. The reason why it is so popular is mainly because of open source and low development costs. I don’t want to talk about this issue again. Some programmers want to improve performance from PHP code. Haha, it’s a bit ridiculous. If the code is not written too badly, how much efficiency can one code improve? If you want to improve the efficiency of the system, use .NET or JSP.
As for the efficiency of PHP, it is only slightly faster than ASP. Besides, the improvement of efficiency is definitely not something that can be solved from the code alone. There are many factors, such as infrastructure, etc.

The above has introduced the quantity of chemical substances in the first year of high school. Writing high-quality PHP programs includes the content of the quantity of chemical substances in the first year of high school. I hope it will be helpful to friends who are interested in PHP tutorials.
