How to test the reflection mechanism in php?

This article mainly introduces the reflection reflection mechanism test examples in PHP. From this article, you can learn some ways to use reflection. Friends who need it can refer to it

Java class reflection is very widely used and almost The core part of all frameworks, PHP programmers never seem to care about reflection. Try to use Java ideas to understand PHP's reflection, which is basically the same as Java. Refer to php manual

ReflectTest.php:

<?php

    if("setQq"==$m->getName()){
