php - 如何在php中从父类获取子类名称

Question

<?php

class parentClass {

    function myChild() {
        echo 'Child Class Name: '.__CLASS__;
    }   
}

class childClass extends parentClass {

}

$childClassObj = new childClass;

$childClassObj->myChild();

输出是

Child Class Name: parentClass

实际上，我期望输出

Child Class Name: childClass

我应该怎么做才能获得输出？

Answer 1

您可以使用get_called_class

<?php
    class parentClass {

        function myChild() {
           echo 'Child Class Name: '.get_called_class();
        }   
    }

    class childClass extends parentClass {

    }

    $childClassObj = new childClass;

    $childClassObj->myChild(); //childClass
?>
