wp_parse_args_deep

[tazotodua]

It would be nice if WP had built-in wp_parse_args for recursive usage (multi-dimensional arrays).

The concept is written here: ​https://mekshq.com/recursive-wp-parse-args-wordpress-function/

I am new to submitting patches, so my applied patch might need correction. thanks.

Thank you for the suggestion and patch, @tazotodua!

This is an interesting idea, but as described in #19888, I don't think it's a good option for core.

For the example you describe in your post, you could just use array_merge_recursive(), instead. wp_parse_args() is mostly just a helper function that runs wp_parse_str() first (in case the args are passed as a string), then runs an array_merge().
