问题描述
我有一个类,它有一些静态的,一些不是静态的方法.它具有静态属性.我试图在所有方法中访问该属性,但找不到正确的语法.
I have a class and it has some static, some not static methods. It has a static property. I'm trying to access that property inside all of it's methods, I can't figure out the right syntax.
我有什么?
class myClass {
static public $mode = 'write';
static public function getMode() {
return myClass::$mode;
}
public function getThisMode() {
return $this->mode;
}
}
有人可以告诉我该代码的实际语法吗?
Can anyone tell me the actual syntax for this one?
推荐答案
对于静态属性,即使在非静态函数中也要使用以下内容
For static properties use the following even inside a non static function
return self::$mode;
之所以这样,是因为无论对象是否已实例化,都存在静态属性.因此,我们只是使用相同的预先存在的属性.
The reason for this is because the static propery exists whether an object has been instantiated or not. Therefore we are just using that same pre-existing property.
