PHP在靜態函數中獲取子類的名稱

Question

是這樣的可能嗎？

<? 
class A 
{ 
    public static function fun() 
    { 
     var_dump(get_class(child)); //bool(false) //should return B 
    } 
} 
class B extends A 
{ 
    public static function fun() 
    { 
     parent::fun(); 
    } 
} 

B::fun(); 
?> 

Answer 1

<?php 
class B extends A 
{ 
    public static function fun() 
    { 
     parent::fun(); 
    } 
} 
class A 
{ 
    public static function fun() 
    { 
     var_dump(get_called_class()); 
    } 
} 

B::fun();

Answer 2

隨着PHP 5.3的，有get_called_class()爲了這個目的：

echo get_called_class(); // yields "B"
