php get_called_class()函數與get_class()函數的區別

get_class (): 獲取當前調用方法的類名； 
get_called_class():獲取靜態綁定后的類名；

class Foo{
      public function test(){
         var_dump(get_class());
      }

      public function test2(){
        var_dump(get_called_class());
      }

      public static function test3(){
        var_dump(get_class());
      }

      public static function test4(){
        var_dump(get_called_class());
      }
   }

   class B extends Foo{

   }

   $B=new B();
   $B->test();
   $B->test2();
   Foo::test3();
   Foo::test4();
   B::test3();
   B::test4();

　　

輸出結果：
string 'Foo' (length=3)
string 'B' (length=1)
string 'Foo' (length=3)
string 'Foo' (length=3)
string 'Foo' (length=3)
string 'B' (length=1)
