how to get term id from current post type instead of name

Question

following code is returning name of all terms associated with my custom Post Type which are under `generetax taxonomy only

$terms = get_the_term_list($post->ID, 'generetax'); 
echo $terms;

Can you please let me know how to get the term_id instead of name? I tried this way

 echo $terms->term_id;

but it is not returning any thing

Update

Ok On rnnung this method

   $terms = get_the_terms($post->ID, 'generetax'); 
            foeach($terms as $term){
                print_r($term);
            }

WP_Term Object ( [term_id] => 3 [name] => Semi [slug] => semi [term_group] => 0 [term_taxonomy_id] => 3 [taxonomy] => generetax[description] => [parent] => 0 [count] => 1 [filter] => raw )

but still $terms->term_id; return nothing on

   $terms = get_the_terms($post->ID, 'generetax'); 
            foeach($terms as $term){
              echo  $terms->term_id;
            }

Answer 1

get_the_terms() will help you. Function return array with terms objects and you can foreach array and retrieve term id for each term attached to post.

Answer 2

If only getting ids of each term in array, no need to foreach each term item, just use php array_column native function :

$terms = get_the_terms($post_id, 'taxonomy');
$terms_ids = array_column($terms, 'term_id');
//output
[array_of_ids]
