Wordpress gets the name of the taxonomy with bullets

How can I get a taxonomy identifier or name using only the taxonomy pool?

I assume I'm looking for the equivalent of get_term_by (), but for taxonomies.

Edit: I must indicate that I am trying to get the tax id for the WooCommerce product attribute.

thank

<?php 
    $term = get_term_by('slug', $slug, 'category'); 
    $name = $term->name; 
    $id = $term->term_id;

WordPress provides a function to get taxonomy information from its bullet.

$taxonomy_details = get_taxonomy( $slug );

This will return the details of the taxonomy as an object that includes various labels for the taxonomy. For example, here is the returned object when called for a standard category taxonomy, for example.get_taxonomy( 'category' );

stdClass Object
(
    [labels] => stdClass Object
        (
            [name] => Categories

, , .

The third (required) argument get_term_by()is the name of the taxonomy itself, and therefore this function cannot be used.

get_taxonomies() cannot be used either because then you have to map the entire rewrite array, which you probably do not have access to.

So the only way I found was to use a private array $wp_taxonomies:

function get_tax_name_from_slug($slug){
  foreach ($wp_taxonomies as $key => $value) {
    if ($value->rewrite['slug'] === $slug){
        return $key;
    }
  }
}

I really hope that Wordpress will provide you with a way to do this without access to their internal data structures.

                    )
                );
