Matching slug terms from one array to those in array of WP_Term objects to output term names

Question

I'm using WordPress's get_terms to return an array of WP_Term objects containing the term_id, name, slug, etc. for the child terms of a given taxonomy. I've saved this array to $tax_terms. I have a different array—$active_filters—containing just the slugs of terms that match certain taxonomy terms; for instance, from a var_dump of $active_filters:

array (size=3)
  0 => string 'term-1' (length=6)
  1 => string 'term-2' (length=6)
  2 => string 'term-3' (length=6)

I'm wondering if there's a way I can run a foreach that will compare this array of term slugs to those in the array returned by get_terms and return the name for any matched slug? So, the example above would output "Term 1", "Term 2", "Term 3". I've tried using array_search but to no avail, thus far. Any assistance is greatly appreciated.

Answer 1

Perhaps array_map ?

This will give you an array of term names which matched your slugs in $active_filters:

$matched_terms = array_map(function($term) use ($active_filters){
    if(in_array($term->slug, $active_filters)){
        return $term->name;
    }
    else{
        return false;
    }

}, $tax_terms);


//remove the empty array elements which came from terms which didn't match a slug
$matched_terms = array_filter($matched_terms);
