Question

I have an object that implements IteratorAggregate and ArrayAccess, which internally contains an array that will be generated when it is accessed.

I want to use array_walk_recursive on this object, but it does not seem to work. It seems that this is either impossible due to the implementation of array_walk_recursive or I just need to add an interface to my object. What am I missing?

Answer 1

Since array_walk_recursive operates on arrays, your object probably has to implement the ArrayAccess interface.
