问个子类对象直接调用基类内被重载的函数的问题?
/// 问题看如下代码
class A
{
function A()

$this->nNum = 1024;
}
function SelfClass()
{
echo "class A
";
}
}

class B extends A
{
function SelfClass()
{
echo "class B
";
}
}
?>

$obj = new B();
$obj->SelfClass(); // 调用B类的函数SelfClass()函数
/* 如何能使用对象obj的基类的SelfClass()函数?
C++下可以写类似的代码$obj->A::SelfClass(),那么PHP可以如何实现呢?*/
?>
