My MySQL class library in PHP, after loading it with include, can only define variables. How to use the functions in it? It is useless to write the function name directly. Please give me a detailed method. Thank you.

Class libraries are generally used for inheritance. Your own project class inherits the extends class library. In this way, you can use the methods and things inside it in your own class. Do you understand this?

I think only referring to it is equivalent to loading But it doesn't say how to use the functions inside. What should I add before using the function inside? I don’t know mainly this.

Directly copy the code encapsulated in the class library into your program, and then call it.

Should I copy it directly? Can't I use include to load it? Is it written like this? If I copy it directly, it will feel very bloated.

Include is also OK
