常量持有$这个类名

Question

Is there a constant in PHP holding the current sub classes name? So that I can write a function like:

namespace test\that;

class MyClass extends ClassA {
}

abstract class ClassA {
    public static function getClassName() {
        return __THIS_CLASS__; // like get_class($this); in a none static method
    }
}

In the end I would do something like this:

namespace test\other;

use test\that\MyClass;

var_dump(MyClass::getClassName()); // --> test\that\MyClass

Is that even possible?

Answer 1

You're probably looking at get_called_class() ; it returns the name of the class the static method is called in.

public static function getClassName() {
    return get_called_class();
}

MyClass::getClassName(); // "MyClass"

Answer 2

How about __CLASS__ ?

Have a look at the constants: http://www.php.net/manual/en/language.constants.predefined.php

Answer 3

You can use PHP's get_called_class() method. To return both parent class and child class names.

get_called_class()
