With the continuous development of IT technology, various programming languages ​​​​are also emerging in endlessly. Among them, PHP, as a widely used scripting language, has been widely used in the development process of web applications. However, a problem inevitably arises - code quality is difficult to guarantee.

To solve this problem, people began to use code review tools to assist developers in quality control.
