如何访问PHP中的静态函数内的私有成员 [英] How to access a private member inside a static function in PHP

问题描述

我在PHP中有以下类

  class MyClass 
 {
 //如何声明我的会员在这里？它需要是私人的
 public static function MyFunction（）
 {
 //如何访问MyMember？ 
} 
} 
  

我完全困惑使用哪种语法

$ MyMember = 0; 和 echo $ MyMember p>

或

private $ MyMember = 0; code> echo $ MyMember

或

$ this-> MyMember = 0; 和 echo $ this-> MyMember

$ b b

有人可以告诉我怎么做吗？

我在OOPS中不强。

如果没有，我应如何声明成员，以便我可以在静态函数中访问它？

解决方案

  class MyClass 
 {
 private static $ MyMember = 99; 
 
 public static function MyFunction（）
 {
 echo self :: $ MyMember; 
} 
} 
 
 MyClass :: MyFunction（）; 
  

请参阅 Visibility and Scope Resolution Operator（:: ）在php手册的oop5章节。

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?
  }
}

I am totally confused about which syntax to use

$MyMember = 0; and echo $MyMember

or

private $MyMember = 0; and echo $MyMember

or

$this->MyMember = 0; and echo $this->MyMember

Can someone tell me how to do it?

I am kind of not strong in OOPS.

Can you do it in the first place?

If not, how should I declare the member so that I can access it inside static functions?

解决方案

class MyClass
{
  private static $MyMember = 99;

  public static function MyFunction()
  {
    echo self::$MyMember;
  }
}

MyClass::MyFunction();

see Visibility and Scope Resolution Operator (::) in the oop5 chapter of the php manual.
