Methods and techniques for studying PHP open source source code_PHP tutorial

I have recently been studying the source code of phpcms. I have been studying it for almost a week. Now I will share some methods of studying php open source source code based on some analysis methods I found on the Internet and my own insights. And some tips.

1. First, the source code must be installed so that it can be accessed through http. Understand what functions the application has and how the URL distributes requests.

2. Browse the directory structure of the source code and understand the functions of each directory.

3. Analyze the source code framework. For example, whether the entrance method is single entrance or multiple entrances, and the calling rules between pages, the pages used by a certain function can be found based on the rules.

4. Be familiar with the coding style of source code, such as variable naming, function and class naming, indentation, layout format, etc.

5. Be familiar with the databases and tables used in the source code. If there are reference documents, you can refer to its technical support documents.

6. After the above steps, I believe everyone has a deeper understanding of this source code. However, this understanding is only superficial. Let’s analyze it in detail from 6 aspects:

1. The specific implementation of the entrance structure and page calling method. If you see tool classes and tool functions while reading, try to familiarize yourself with them. By analyzing the tool classes and tool functions used in the source code, you can learn a lot of programming skills. You can improve your programming skills. This step of analysis can learn the system architecture of the source code.

2. Combining some security rules, study how this source code implements security design. This can improve your awareness and skills in safety.

3. If there is a template engine, study the source code of the template engine. Roughly consider several aspects such as implementation, efficiency, and ease of use.

4. Study the various functional modules of the system, so that you can not only learn programming skills but also open up your own programming ideas. Next time you encounter similar application development, you will be handy.

5. Study the design patterns used in the system. The design patterns used to implement the same function may be very different. Comparing the application analysis and design patterns we have done before can greatly improve our ability to control the code.

7. Research the optimization of source code in terms of access pressure, execution efficiency, system efficiency, and database query. Of course, the premise of this is that the source code you study must have these considerations in mind.
