PHP 从对象打印键? [英] PHP Print keys from an object?

问题描述

我有一个对象 BIRD，然后有 [0] 到 [10]，每个数字都有一个副标题，如虫子"或甲虫"或蚊蚋"，以及每一个的值.

I have an object BIRD and then there is [0] through [10] and each number has a subheading like "bug" or "beetle" or "gnat" and a value for each of those.

我想打印

BIRD 
    [0]
       bug = > value 

我在任何地方都不知道如何做到这一点 - 有关于 PUBLIC、PRIVATE 和 CLASS 的讨论，这就是我失败的地方

I can't find out how to do this anywhere - there is talk of PUBLIC and PRIVATE and CLASS and that's where I fall off

推荐答案

我可能是错的，但尝试使用 array_keys 使用对象作为参数.我相信这在 php 中是可能的.http://php.net/manual/en/function.array-keys.php

I could be wrong but try to use array_keys using a object as parameter. I believe that is possible in php. http://php.net/manual/en/function.array-keys.php

无论如何，请阅读反射.

Anyway, read about reflection.
