laravel方法与特征与立面之间有什么区别 [英] What is the difference between laravel method vs trait vs facade

问题描述

简而言之，比较这三个最简单的方法是什么?

In a nutshell what would be the easiest way to compare the three?

方法vs特质vs门面

干杯！

推荐答案

它们并没有真正的比较，因为它们是完全不同的东西.

They don't really compare because they're really different things.

方法是属于类的函数.

class MyClass
{
     public function this_is_a_method() { }
}

特质是在类之间共享代码的一种手段.一个特性无法实例化，而是包含在另一个类中.类和特征都可以定义方法.

A trait is a means of sharing code between classes. A trait cannot be instantiated, but rather is included into another class. Both classes and traits can define methods.

trait MyTrait
{
     public function this_is_a_method() { }
}

现在我有了这个特征，我可以更新MyClass来使用这个特征.

Now that I have this trait I can update MyClass to use this trait.

class MyClass
{
     use MyTrait;
}

您可以将特征视为复制和粘贴.现在MyClass复制MyTrait中定义的方法，以便您可以执行此操作.

You can think of traits as copy and paste. Now MyClass copies the methods defined in MyTrait so you can do this.

$class = new MyClass();
$class->this_is_a_method();

方法和特征都是PHP的功能.立面是Laravel的功能.外墙只是语法糖，可以帮助您从容器中获取服务.

Both methods and traits are features of PHP. Facades are a feature of Laravel. Facades are simply syntactic sugar to help get services out of the container.
