PHP中的静态和非静态调用 [英] Static and Non-Static Calling in PHP

问题描述

好的，我正在学习这段代码

ok I have this code, that I'm studying

 class scope{

    function printme(){
        return "hello";
    }

    public static function printme(){
        return "hello"; 
    }

 }

$s = new scope();
echo $s->printme(); //non-static call
echo "<br>";
echo scope::printme(); //static call

现在，这实际上不是我项目的代码，但这是我想要做的事情

Now, this is not really the code of my project but these are the things I want to do

1. 我想创建一个包含静态和非静态函数的类.
2. 我希望在静态和非静态调用中都可以使用该功能.

由于非静态函数具有很多操作，因此我还需要将其称为静态函数，这样就无需实例化该类.这可能吗?还是真的需要将该函数重写为另一个函数或类?

As non-static function has a lot of operations on it, I also need to call it as a static function so that I will not need to instantiate the class. Is this possible? or I really needed to rewrite the function to another function or class?

注意:告诉我我是否已经在做一些不好的编程了.

NOTE: tell me if I'm doing some bad programming already.

推荐答案

以下是规则:

Here is the rule:

静态方法可以用于静态方法，也可以用于非静态方法.

A static method can be used in both static method and non-static method.

非静态方法只能在非静态方法中使用.

A non-static method can only be used in a non-static method.
