PHP:对象上的array_map? [英] PHP: array_map on object?

问题描述

我正在尝试编写一个函数，该函数格式化对象中的每个(字符串)成员/变量，例如使用回调函数.变量名对我来说是未知的，因此它必须适用于所有类的对象.

I'm trying to write a function that formats every (string) member/variable in an object, for example with a callback function. The variable names are unknown to me, so it must work with objects of all classes.

如何用对象实现类似于array_map或array_walk的东西?

How can I achieve something similar to array_map or array_walk with objects?

推荐答案

使用

use get_object_vars() to get an associative array of the members, and use the functions you mentioned.

顺便说一句，您也可以像在数组上一样在对象上进行foreach操作，这有时也很有用.

btw, you can also do a foreach on an object like you would on an array, which is sometimes useful as well.
