PHP从子类中获取重写的方法 [英] PHP get overridden methods from child class

问题描述

鉴于以下情况:

<?php

class ParentClass {

    public $attrA;
    public $attrB;
    public $attrC;

    public function methodA() {}
    public function methodB() {}
    public function methodC() {}

}

class ChildClass extends ParentClass {

    public $attrB;

    public function methodA() {}
}

如何获取在ChildClass中重写的方法(最好是类var)的列表?

How can I get a list of methods (and preferably class vars) that are overridden in ChildClass?

谢谢， 乔

已修复错误扩展.任何方法，而不仅仅是公共方法.

Fixed bad extends. Any methods, not just public ones.

推荐答案

反射是正确的，但是您必须这样做:

Reflection is correct, but you would have to do it like this:

$child  = new ReflectionClass('ChildClass');

// find all public and protected methods in ParentClass
$parentMethods = $child->getParentClass()->getMethods(
    ReflectionMethod::IS_PUBLIC ^ ReflectionMethod::IS_PROTECTED
);

// find all parent methods that were redeclared in ChildClass
foreach($parentMethods as $parentMethod) {
    $declaringClass = $child->getMethod($parentMethod->getName())
                            ->getDeclaringClass()
                            ->getName();

    if($declaringClass === $child->getName()) {
        echo $parentMethod->getName(); // print the method name
    }
}

属性相同，只是您将使用getProperties().

Same for Properties, just you would use getProperties() instead.
