Course Introduction：Chapter 4 Class and Object-Oriented Programming In the previous chapters, we learned Kotlin's basic language knowledge, type systems and other related knowledge. In this chapter and the next chapter, we will learn Kotlin's support for object-oriented programming and functional programming. In this chapter, we introduce Kotlin's object-oriented programming. 4.1 A brief history of object-oriented programming In the late 1950s, when writing large programs in the FORTRAN language, because there was no encapsulation mechanism, the variables at that time were all "global variables", so variable name conflicts would inevitably occur frequently. In ALGOL60, program blocks identified by Begin-End are used to make the variable names inside the block local to avoid them from outside the block in the program

Course Introduction：Object-oriented programming (OOP for short) is not only a need for developing large-scale projects, but also a tool for analyzing problems. PHP has complete object-oriented programming capabilities and can complete the development of large-scale commercial projects. This course combines the object-oriented technology in PHP , break it apart and crush it, and I’ll tell you slowly.

Course Introduction：**Thinking**: At the beginning of PHP learning, our code first appeared in the HTML mixed state, and then slowly became independent. Later, the PHP code was separated into different scripts, loading and calling each other. What exactly is the logic in this? **Introduction**: In fact, from the perspective of realizing business functions, any mode is acceptable. However, project development often involves team collaboration, which requires teamwork and the maintainability of later code. This leads to the practice of classifying code and dividing it into files. We have different positions for code development, and each method has its unique advantages and disadvantages.
