如何在 PHP 中的静态函数中访问私有成员
我在 PHP 中有以下类
I have the following class in PHP
class MyClass
{
// How to declare MyMember here? It needs to be private
public static function MyFunction()
{
// How to access MyMember here?
}
}
我完全不知道该使用哪种语法
I am totally confused about which syntax to use
$MyMember = 0; 和 echo $MyMember
或
private $MyMember = 0; 和 echo $MyMember
或
$this->MyMember = 0; 和 echo $this->MyMember
谁能告诉我怎么做?
我不太擅长 OOPS.
I am kind of not strong in OOPS.
你能做到吗?
如果没有，我应该如何声明成员以便我可以在静态函数中访问它?
If not, how should I declare the member so that I can access it inside static functions?
推荐答案
class MyClass
{
private static $MyMember = 99;
public static function MyFunction()
{
echo self::$MyMember;
}
}
MyClass::MyFunction();
