Order by slug in get_terms with multiple taxonomies

Question

I am builing a search engine where I need to search in 2 different taxonomies and sort them by slug. I got this code to do so.

$search = sanitize_text_field( $_POST[ 'search' ] );
$content = '';
$terms = get_terms(array(
    'taxonomy' => array('apartments','houses'),
    'search' => $search,
    'orderby' => 'name',
    'order'             => 'DESC',
    'hide_empty' => true
));

Right now the result is:

• Apartment A
• Apartment B
• House A
• House B

and i would like it to be like that:

• Apartment A
• House A
• Apartment B
• House B

Any idea as I run out of at the moment ;) I would like to avoid JS at that moment.

Answer 1

$keys = array_column($terms, 'slug');
array_multisort($keys, SORT_ASC, $terms);

That did the trick and let me sort terms in that muli array.
