PHP: array_map on object?

Question

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.

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

Answer 1

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

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