Talking about the struct of go

Always thought that struct It is used to store data , Until today, when writing code ,goland Give me a hint

f That's what we usually say field

m Namely method.

Think about the classes we usually write , Isn't it just a class ？ It's just god The encapsulation of is based on the case of the initial letter . also init() It can also be seen as __construct() Initialize things ( This description is not very accurate , stay go It's all about &struct{} To initialize .)

<?php
class A {
    protected $a;
    
    public function aaa(){
    
    }
}
?>
