Question

说我有这个课程

class Grandpa
{
    public function call(){
        // Well, I want to know who calls me here
    }
}

class Father extends Grandpa
{
}

class GrandsonOne extends Father
{
}

class GrandsonTwo extends Father
{
}

现在，我像这样调用Grandson类中的函数：

GrandsonOne::call();
GrandsonTwo::call();

我怎样才能找出谁叫了？

Answer 1

您正在寻找的是get_called_class功能。从PHP文档： -

Gets the name of the class the static method is called in.

所以

class Grandpa
{
    public function call()
    {
        // Well, I want to know who calls me here
        echo get_called_class();
    }
}

将输出被调用类的名称。

哪位孙子打电话给我？
