PHP包括CLASS中的文件[关闭]

Question

I want to include file in PHP class.

Why I want to include file ?

there are too many functions in my class, and its very hard to find them. So I want to put functions in a file by their type, and include them by calling the file in class.

like: all function for head will be inside a head.php file.

So please tell me how do I include files in class ?

Answer 1

What if you extend the class and put functions in it?

class Second extends Main
{

}
